Henri Becquerel Research Paper
Henri Becquerel was a Physicist, while doing some research, he found radioactivity. Henri was born in Paris in 1853, he was born into a family of
scientists. Alexander Becquerel, Aurelie Quenard, and Antoine CГ©asar were his family. His father and grandfather were scientists as well. His father
was an expert on solar radiation and his grandfather had invented an electrolytic method for extracting metals from their ores. He learned about physics
and chemistry through his university and joined the government department in 1874. He was appointed professor of profiled physics in the department
of natural history at the Paris museum. His discovery to radioactivity helped a lot of other scientists. If Henri hadn't discovered it Ernest Rutherford

Essay about Cancer and Terry Tempest Williams' Refuge
Cancer and Terry Tempest Williams' Refuge
"I cannot prove my mother, my grandmothers, along with my aunts developed cancer from nuclear fallout in Utah. But I can't prove they didn't."
Epilogue, Refuge
In Terry Tempest Williams's Refuge, death slowly claimed almost all of the women of her family. Death took Williams' family members one by one
just one or two years apart. In every case, the cause was cancer. Williams insisted in the epilogue that fall–out from the 1951–62 nuclear testing in Utah
brought cancer to her family. Because there are many other causes of cancer, such as genetic andenvironmental factors, it is hard for one to insist that
nuclear fall–out causes cancer. Therefore, it is important to find out how and why ... Show more content on Helpwriting.net ...
For example, Iodine 131 causes thyroid cancer. It is a substance that dissolves into liquid such as water and milk. Other chemicals such as
Strontium–90 and Cesium 147 as well get into water, milk, soil, food and vegetables that we eat and cause bone, skin cancer and leukemia. Chemicals
like Strontium–90 and Cesium–147 remain for up to 200 to 300 years in the atmosphere (CancerSource.)
The United States tested nuclear bombs, "215 A– and H–bombs" (www.nukewatch.com) above ground between 1951 and 1963 in the Nevada Test
Site. Fifty years later, the U.S government studies stated that over 80,000 people who lived or were born in the U.S suffered from cancer caused by
radioactive fall–out from nuclear testing. Over 15,000 of them died. Many of whom were from the states close to the testing sites, called the
"downwinders," Utah, Idaho and other states. From the Nevada Test Site the winds carried nuclear radiation fallout, filled with "iodine–131" which
caused "75,000 thyroid cancers, ten percent of which are estimated to have been fatal, and strontium–90 and cesium–137, which are dangerous for
between 280 and 300 years," (nukewatch) likely causes of bone and skin cancer and leukemia. Therefore, there is some strong evidence that nuclear
fall–out in the 1950s did cause cancer.

Compare And Contrast Marie And Carrie Curie
Radiation is energy that comes from a source and travels through some material or through space. Pierre and Marie Curie were partners that had both
become interested in the discovery Henri Becquerel made which was the discovery of radioactivity. Marie and Pierre Curie came up with the term
"radioactivity" to describe Becquerel's discovery. Marie and Pierre extracted uranium from ore and compared the pure uranium to the extracted uranium
ore samples. They found that the uranium ore samples contained more radioactivity. Marie's research concluded that the two uranium ore samples,
pitchblende and chalcocite, were more radioactive than the pure uranium and so because of the high radioactivity of both of the samples there had to

Nuclear Energy Is The Energy
What is Nuclear Energy
"Nuclear energy is the energy in the nucleus, or core, of an atom." Each nucleus has two kind of particles
Neutrons
Protons
There are two process to release nuclear energy
Fission and fusion
Process
Fission
A atom of one element is divided to create two small atom of different elements
Fusion
During this process, nuclear reactors use uranium to release energy
Two atoms are combined to made a large atom
This energy produces heat and warms the reactors cooling agent (usually water, liquid metal or molted salt)
The heat produces steam that turns on the turbines
Turbines propel generators that generates energy
BENEFITS
Low Pollution

The Harsh Reality of Keeping Away From Radioactivity
Radioactivity is a looming threat that many people do not seem to know about. Ever since the Fukushima disaster in Japan, the internet has been
swarming with reports about how the radiation can reach the West Coast and harm Californians. This has been confirmed by experts; radioactivity
was expected to show up in April and has already been found in kelp along the sea. Radioactivity is a serious threat to humans, and people should
be more aware of the risks related to it, especially now, when there are signs of radioactivity in the West Coast. The main argument that people use
to keep themselves from accepting the harsh reality of radioactive poisoning is that since there have been no radioactive leaks in the United States
recently, we are not at risk. This also is untrue; back in April, there was a radioactive leak in New Mexico. So far, doses of radiation to the
surrounding population are low, but even those low levels of radioactivity can have harmful effects on the body in the long term. So what are these
harmful effects? To answer this question, we need to understand how radioactive isotopes decay. There are many different elements, and each has its
own radioactive isotopes. For example, one of the common plutonium isotopes produced by man is plutonium–239. When this radioactive isotope
decays, it produces energy. This energy is radioactivity. When the isotope decays, it produces alpha, beta, and gamma particles. These particles are

Radioactive waste. What is it? Radioactive waste is what the name says it is; radioactive and waste. Basically, it is anything that has been exposed to
a radioactive nuclear substance and is not in use of anyone anymore so it is declared as trash. Also bear in mind that any definitions or information
varies in different countries. Now, there are many different types of waste, ranging from the least amount of hazard to the greatest amount of hazard.
The ones with the least amount of radioactivity tend to have shorter lives. They decay in less than 30 years and are called, "short–lived". The ones with
a greater amount of radioactivity perish in more than 30 years and are called, "long–lived". Let's break these types of wastes into three parts.

where it will be stored in the mean time that will not affect their safety. As Muller explains, "Even after 100,000 years the radiation will still be above

considerably high as one might think? According to Richard Muller the risk of not depositing the waste is higher the not doing so. He explains
"When I work out the numbers, I find the dangers of storing waste at Yucca Mountain to be smaller compared to the dangers of not doing so, and
significantly smaller than the dangers we ignore."(Muller 254) Regardless of the ideas from the politicians and scientists that more research is need,

Maria Sklodowska Research Paper
Maria Sklodowska was born on November 7, 1867. She was born in Warsaw, Poland by her mother, Bronsitwa, and father, Ladislas. She was the
youngest child, and had three older sisters and one brother. Ladislas was a math and physics teacher, which later inspired Marie's interest for the
sciences. Bronsitwa passed away of tuberculosis when Marie was just eleven years old. She also had a sister, Bronya, who Marie worked to support
since their mother had passed. Eventually, she married Pierre Curie and had two daughters, Irene and Eve. Even though her family life was a struggle,
Marie still managed to become a legendary physicist later in life. Curie's father, Ladislas, being a physics and mathematics educator was the spark
which got her interested. From a young age, Curie was an excellent student; always intrigued by her father's profession. Curie and her sister always
dreamed of education at an elite level. However, with financial lacking and no mother, Marie and Bronya helped one another pay for a secondary

While working on her dissertation she became fascinated by the work from Henri Becquerel. Becquerel's discovery of uranium salts emitting rays
inspired her to conduct further research. Within a couple months of beginning her research she made two important discoveries that "led her to
formulate the theory that the rays were the result of something happening within the atom itself, a property she called radioactivity" (Goldsmith). She
discovered that the rays were emitted from the anatomical structure of the atom and the outcome was not due to the interaction of molecules. Pierre
Currie later abandoned his own research in crystals to help his wife in testing minerals that revealed high levels of radioactivity. From Marie Curie's
testing she concluded that a new more powerful element was responsible for the high levels of radioactivity. The Curies confined their research to the
mineral pitchblende because it emitted the strongest rays. They then diligently and progressively separated pitchblende by chemical analysis. They
measured the radioactivity of the separate components. "In July, 1898, she and Pierre successfully extracted an element from this ore that was even
more radioactive than uranium; they called it polonium in honor of Marie's homeland" (Goldsmith). Within that same years they identified a more
radioactive element. This element which was embedded in the pitchblende was named radium. To prove their discovery they needed to isolate a pure
form of this element. Which was no easy task, considering that these elements were extremely small and almost unnoticeable. In 1902 they were able
to isolate enough radium to confirm its existence. Marie Curie then received a doctorate degree from the Sorbonne University, making it the first
awarded to a women in Europe. In 1903 Pierre and Marie Curie and Henri Becquerel where jointly awarded the Nobel Prize in physics for their

eventually repaired and it continued working as it had before, even though it had many more light breakdowns than it had before. Marie and her
sister had worked out a plan as well. First, they would save up enough money between them to send Marie's sister to college in France first. Then,
they would send Marie when they had enough money. Of course, there was a small issue. Since the college was in France, all of the lectures were

know some French, so it was easy for her to learn the rest of the language. But after these early issues, things seemed to be going well. There was
nothing major that stopped them. Kingda Ka ran smoothly for quite some time and Marie's interest in science really grew. This part in their lives

However gamma can be extremely dangerous because they are a very powerful source of power, if they delivered in an unmonitored and uncontrolled
way they can kill humans, animals and plants. Gamma rays however can also disrupt the physical properties of materials. They can cause plastics and

that uranium had absorbed the sun's energy, then released to create an x–ray. His first experiment had failed due to an overcast over in Paris, but this
didn't stop Becquerel from developing his photographic plates. Although Becquerel was the one to discover radiation, the term radioactivity was

Some forms of radiation can be man–made or found naturally, but both are pretty harmful. When radiation merges with molecules in living cells, it
can severely damage them. This cell may become cancerous if the DNA has been damaged. This will mean that it can't repair itself. The cell will go
out of control, causing serious health issues, meaning it can increase the risk of both animals and to ourselves in getting cancer. Although radiation is
harmful to living cells, too much of it being merged into a living cell will more likely die completely. Sunlight, which is one of the most essential
forms of radiation can be extremely harmful in large quantities.
Overall, radioactivity has both positive and negative effects on people and the environment. Radioactivity is used in modern day medical equipment
and radiotherapy. But alongside this, radioactivity can be really harmful to the environment and to people through UV rays (from the sun), which can

Should Yucca Mountain Be A Nuclear Waste Disposal Site?
Introduction:
The task we are in charge with is determining if Yucca Mountain is a suitable long term nuclear waste disposal site, if it is a suitable short term
nuclear waste site until other sites are found or other scientific ways to dispose of the waste are found, and lastly if Yucca Mountain is not
determined to be a long or short term option for nuclear waste disposal. Option one would be to go ahead with the Yucca Mountain plan of long term
storage since it is the only answer we have currently for nuclear waste. Option two would be to use Yucca Mountain as a short term storage unit until
we find another more stable site or if we find a way to deactivate the radioactivity in the waste. The last option is to not use Yucca Mountain as a short
or long term storage unit because the site is shown to have water leakage and would therefore contaminate the surrounding area.
Option One:
In 1987 Congress amended the Nuclear Waste Policy Act (NWPA) which made the department of energy (DOE) responsible for investigation and
determination of the Yucca Mountain site. For more than twenty years the DOE has investigated and come up with preliminary designs for the
mountain. Option one is to continue with the plan to use Yucca Mountain as the permanent storage site for nuclear waste. Yucca Mountain would

What does the word radiation bring to mind? Some picture nuclear bombs, others a nuclear power plant producing radioactive waste. However,
one of the first uses of radiation was for medical treatment, not destruction or energy. The scientist who discovered this potential was Maria
Salomea Sklodowska, also know as Marie Curie. Michael Hart, in his book The 100, stated, "It seems to me, however, that her great fame is based
not so much upon the importance of the scientific work she did as upon the fact that a woman did it." (Hart 515). Some people would argue that
Marie Curie's research was influential because she grew up in Russian controlled areas of Poland, where learning about certain things was not allowed,
she isolated the elements polonium and radium in pitchblende, and that her work helped advance the development of nuclear technologies. Growing
up, Marie Curie was not in the best of situations, however this gave her the hunger to learn more. She was born in the Russian controlled Kingdom of
Poland on November 7, 1867 (Britannica). Her mother was a principal at a local school, and her father a physics teacher. When Marie was only five her
mother developed tuberculosis, separating her from her family until the time of her death. Despite this Marie learned incredibly well, ... Show more

Female Scientists In The 1800's Essay
During the 1800's, there were not a lot of female scientists. Marie Curie became the first woman to receive a nobel prize, and also the first to receive
two of them. She was a Polish–French physicist and chemist who discovered two elements and was famous for her work with radioactivity. She got her
love of science from her father, a physics and mathematics teacher. She moved to Paris to further her education and there met her future husband, Pierre
Curie, and took his place at Sorbonne when he passed away as the first women to hold that position. Those were not the only thing she accomplished
as a female scientist in the 1800's. Marie paved the way for many more female scientists in the future. Marie Curie was extremely intelligent as a child.

When Henri Becquerel discovered radioactivity in 1896, it inspired Marie and Pierre to investigate it further. They researched a lot of substances for
any signs of radioactivity, and discovered something that was more radioactive than uranium. They discovered radium, an element that damaged tissue,
so they used that to fight against cancer. "They found that the mineral pitchblende was more radioactive than uranium and concluded that it must
contain other radioactive substances. From it they managed to extract two previously unknown elements, polonium and radium, both more radioactive
than uranium" (Nobel Media). These discoveries led to radium being used to treat cancer and other diseases, and them getting their first Nobel Prize
in Physics in 1903. After Pierre passed away, she continued with her own studies. Marie successfully isolated radium and proved its existence. She
also studied the properties and compounds of these radioactive elements. "She also documented the properties of the radioactive elements and their
compounds. Radioactive compounds became important as sources of radiation in both scientific experiments and in the field of medicine, where they
are used to treat tumors" (Nobel Media). This discovery led to the further development of X–rays and her receiving her second Nobel Prize in

How Does Nuclear Decay Place
Discussion Question 1 Why and how does atomic nuclear decay take place? Explain. Atomic nuclear is a phenomenon also known as radioactivity.
According to NDE–ED the stability/instability of the nucleus is linked with the paring of spins between neutrons and the pairing of spins between
protons. In a non–radioactive, isotopes are found that a nuclei having even numbers of protons and neutrons to be more abundant. The even numbers
help with spin paring as the odd numbers indicate the unpaired spins. Nuclei with an odd number of neutrons or protons may indicate less stability
compared to a nucleus with even numbers. However, the isotopes that are considered the least stable are the odd number of neutrons and protons
(NDE–ED, 2016). The numbers... Show more content on Helpwriting.net ...

Radioactivity Lab Report
Objective
Radioactivity is present all throughout the environments on earth, which relates to the unstable atomic nuclei. Going into detail, radioactivity occurs in
unstable atomic nuclei and is caused by the spontaneous disintegration of atomic nuclei. Radiation is used in numerous ways that are used in
experiments and medical procedures. In this article, radioactivity will be defined, the three types of radioactivity will be explained, and the different
methods of radiation will be illustrated.
Introduction Nuclei are formed with a higher stability after unstable atomic nuclei spontaneously decompose, and this process is called radioactivity.

The alpha particles have an atomic mass of 4 and a charge of +2. When an alpha particle is released from the nucleus, the mass number of the particle
decreases by four units and the atomic number decreases by two units. An example of this would be where the helium nucleus is the alpha particle. The
energy is a collection of stable nucleons, and those heavier nuclei that can be perceived as collections of alpha particles, such as carbon–12.01 or
oxygen–16.00 are also stable. Beta radiation is a stream of electrons that are called beta particles. When the beta particle is released, a neutron is
transformed to a proton in the nucleus, thus maintaining the mass number of the nucleus. Although, the atomic number increases by one unit. An
example of this occurring is when the electron is the beta particle. Pursuing this further, gamma rays are high–energy photons with a very short
wavelength of 0.0005 to 0.1 nm. The emission of gamma radiation results from an energy change within the atomic nucleus. Gamma emission changes
neither the atomic number nor the atomic mass. Alpha and beta emission are often accompanied by gamma emission, as an excited nucleus drops to a
lower and more stable energy

Marie Curie was born in Warsaw, Poland on November 7, 1867. In her earlier years of research was able to develop methods for separating radium
from radioactive. Marie and Pierre her husband did many studies that examined many substances and minerals in order to find signs of radioactivity.
From studies done, they learned that the materials that they examine contained known radioactivity. The major elements that they studied were uranium
and thorium, which were found to have intensity radiation. Marie also discovered that because these elements were able to emit radiation it did not
depend on the arrangements of the atom, but it could also be linked to the interior of the atom itself. From this discovered she find two new radioactive
elements radium and polonium. ... Show more content on Helpwriting.net ...

The exposure to the radiation released will not only result in heightened risks for cancer in populations, but may also result in other, non–cancer related
health problems such as thyroid diseases, visual impairment, circulatory diseases, hereditary disorders and teratogenic defects (developmental defects
in fetuses). It is important that exposure to radiation be estimated so that cancer risks can be estimated and appropriate responses and health measures
can be implemented by governments to deal with future development in health problems related to the release of radiation from Fukushima. In 2013
the World Health Organization released its health risk assessment for the Fukushima–Daiichi Nuclear disaster concluding that for the general
population "the lifetime risk for some cancers may be somewhat elevated above baseline rates for certain age and sex groups that were in the areas
most affected" and that disease attributable to the disaster is likely to remain below detectable levels. In 2012 Ten Hoeve and Jacobson provided the

Nuclear Energy As A Safe And Reliable Clean Energy...
When nuclear energy was first put into practice the public was fascinated by the new energy source that emerged from the atom and its efficiency.
However, public fascination has turned to fear due to accidents at nuclear reactors and the dangers of radioactivity. While the dangers are apparent,
advancements in technology and safety mechanisms make nuclear energy a safe and reliable clean energy alternative. In a time of growing
environmental concerns of CO2 emissions and dependence of fossil fuels society should not let its fears from the past limit its future in a safe and
clean energy alternative.
As technology advances society's need for energy grows exponentially. Nuclear energy can help provide the energy that society desperately needs, but
there is a lot of controversy around nuclear power. Many people are afraid that potential risks that arise when there is a disaster and the long term
health effect of radiation. Others are concerned with the storage practices for radioactive material. These concerns are always prevalent in nuclear
discussions and an implicit bias and stigma around nuclear energy especially in the United States. The public's fear can lead into decisions based only
on emotion when controversial decisions should be made with a clear and unbiased mind. It is important that people understand and learn all of the

The Pros And Cons Of Radioactivity
Radioactivity has been around since the 1800s. It is very popular in the medical field. It is used my many professionals to help diagnose and treat
people every single day. Although it does have some advantages and disadvantages, people still use it to this day. Radioactivity is defined as "the
spontaneous emission of particles". (Nuclear Energy). Radioactivity is caused by an unbalanced nucleus in the cell. This happens because there is either
an uneven number of protons and/or neutrons. When this happens, the element is considered to have multiple isotopes. Anisotope is an atom with the
same number of protons but a different number of neutrons. Thus, they have different atomic weights. This is important to know because there is a
such thing as a radioactive isotope. These elements just have additional energy, and they release radiation in different forms. "There are over 800
radioactive isotopes, some of which are natural and some synthetic." (Helmenstine). Radioactive elements can be both artificial and natural. However,
in medicine, most of them are more than likely synthetic, since they are the most popular types. The use of radioactive elements in medicine is still
growing to this day. Many oncologists use it to treat their patients who have cancer. Many cancer patients use this option. They use the radiation to kill
off cancer cells. X–ray technicians or radiologists will also use it to administer x–rays to people who may have a broken bone, or need an MRI. The
patient is injected with a radioactive material that helps the doctor be able to see inside the body better, whether it be with pictures or ultrasound.
Radioactive material is defined as "material that contains radioactivity and thus emits ionizing radiation. It may be material that contains natural
radioactivity from the environment or a material that may have been made radioactive." (The Healthy Physics Society). This happens when someone
needs a colonoscopy. They have to drink or are injected with this liquid that helps their organs and all other masses in the body be seen better by the

But I can't prove they didn't." Epilogue, Refuge In Terry Tempest Williams's Refuge, death slowly claimed almost all of the women of her family. Death took Williams' family members one by one just one or two years apart. In every case, the cause was cancer. Williams insisted in the epilogue that fall–out from the 1951–62 nuclear testing in Utah brought cancer to her family. Because there are many other causes of cancer, such as genetic andenvironmental factors, it is hard for one to insist that nuclear fall–out causes cancer.

It is a substance that dissolves into liquid such as water and milk. Other chemicals such as Strontium–90 and Cesium 147 as well get into water, milk, soil, food and vegetables that we eat and cause bone, skin cancer and leukemia. Chemicals like Strontium–90 and Cesium–147 remain for up to 200 to 300 years in the atmosphere (CancerSource.) The United States tested nuclear bombs, "215 A– and H–bombs" (www.nukewatch.com) above ground between 1951 and 1963 in the Nevada Test Site. Fifty years later, the U.S government studies stated that over 80,000 people who lived or were born in the U.S suffered from cancer caused by radioactive fall–out from nuclear testing. Over 15,000 of them died. Many of whom were from the states close to the testing sites, called the "downwinders," Utah, Idaho and other states. From the Nevada Test Site the winds carried nuclear radiation fallout, filled with "iodine–131" which caused "75,000 thyroid cancers, ten percent of which are estimated to have been fatal, and strontium–90 and cesium–137, which are dangerous for between 280 and 300 years," (nukewatch) likely causes of bone and skin cancer and leukemia. Therefore, there is some strong evidence that nuclear fall–out in the 1950s did cause cancer.

Pierre and Marie Curie were partners that had both become interested in the discovery Henri Becquerel made which was the discovery of radioactivity. Marie and Pierre Curie came up with the term "radioactivity" to describe Becquerel's discovery. Marie and Pierre extracted uranium from ore and compared the pure uranium to the extracted uranium ore samples. They found that the uranium ore samples contained more radioactivity. Marie's research concluded that the two uranium ore samples, pitchblende and chalcocite, were more radioactive than the pure uranium and so because of the high radioactivity of both of the samples there had to be additional radioactive ...

  • 7. The Harsh Reality of Keeping Away From Radioactivity Radioactivity is a looming threat that many people do not seem to know about. Ever since the Fukushima disaster in Japan, the internet has been swarming with reports about how the radiation can reach the West Coast and harm Californians. This has been confirmed by experts; radioactivity was expected to show up in April and has already been found in kelp along the sea. Radioactivity is a serious threat to humans, and people should be more aware of the risks related to it, especially now, when there are signs of radioactivity in the West Coast. The main argument that people use to keep themselves from accepting the harsh reality of radioactive poisoning is that since there have been no radioactive leaks in the United States recently, we are not at risk. This also is untrue; back in April, there was a radioactive leak in New Mexico. So far, doses of radiation to the surrounding population are low, but even those low levels of radioactivity can have harmful effects on the body in the long term. So what are these harmful effects? To answer this question, we need to understand how radioactive isotopes decay. There are many different elements, and each has its own radioactive isotopes. For example, one of the common plutonium isotopes produced by man is plutonium–239. When this radioactive isotope decays, it produces energy. This energy is radioactivity. When the isotope decays, it produces alpha, beta, and gamma particles. These particles are also a part of a general class of ... Get more on HelpWriting.net ...

Basically, it is anything that has been exposed to a radioactive nuclear substance and is not in use of anyone anymore so it is declared as trash. Also bear in mind that any definitions or information varies in different countries. Now, there are many different types of waste, ranging from the least amount of hazard to the greatest amount of hazard. The ones with the least amount of radioactivity tend to have shorter lives. They decay in less than 30 years and are called, "short–lived". The ones with a greater amount of radioactivity perish in more than 30 years and are called, "long–lived". Let's break these types of wastes into three parts. Low–level waste (LLW), Intermediate–level waste (ILW), and High–level waste (HLW).

Despite the overwhelming concerns of citizens, Richard Muller believes the dangers associated with the transportation and deposit of nuclear waste is not as paramount as the issue may seem. The concepts that seems most alarming to the public are the number of year it takes for the radioactivity of the waste to subside and where it will be stored in the mean time that will not affect their safety. As Muller explains, "Even after 100,000 years the radiation will still be above 10% of the level it had when it left the reactor."(Muller 254) As a solution, the US government has created a prototype of a nuclear waste ...

Scientists have even tried to develop new alternative such as sending the waste to the sun or sinking it to the bottom of the ocean. Although this is a problem that needs to be addressed, are the effect as considerably high as one might think? According to Richard Muller the risk of not depositing the waste is higher the not doing so. He explains "When I work out the numbers, I find the dangers of storing waste at Yucca Mountain to be smaller compared to the dangers of not doing so, and significantly smaller than the dangers we ignore."(Muller 254) Regardless of the ideas from the politicians and scientists that more research is need, Richard Muller argues that will be of no use. Just the fusion fragments will take about 10,000 years to become as radioactive as the uranium mined from the grounds. There in no amount of research that can predict were our society and planet will be like in 10,000 years. Muller emphasizes how "Ten thousand years ago humans had just discovered agriculture.

She was the youngest child, and had three older sisters and one brother. Ladislas was a math and physics teacher, which later inspired Marie's interest for the sciences. Bronsitwa passed away of tuberculosis when Marie was just eleven years old. She also had a sister, Bronya, who Marie worked to support since their mother had passed. Eventually, she married Pierre Curie and had two daughters, Irene and Eve. Even though her family life was a struggle, Marie still managed to become a legendary physicist later in life. Curie's father, Ladislas, being a physics and mathematics educator was the spark which got her interested. From a young age, Curie was an excellent student; always intrigued by her father's profession. Curie and her sister always dreamed of education at an elite level. However, with financial lacking and no mother, Marie and Bronya helped one another pay for a secondary education.

Marie Curie is the pioneer of radiation research and has made many contributions to the health care field, in particular, to that of radiologic sciences. Curie's accomplishments as a physicist and chemist have brought about enormous scientific breakthroughs in Radioactivity. These discoveries have paved the way for how radiology is practiced today.

Curie was exceptionally brilliant and had an obsessive thirst for knowledge. However, Poland at this time was overruled by Russia ... Show more content on Helpwriting.net ... While working on her dissertation she became fascinated by the work from Henri Becquerel. Becquerel's discovery of uranium salts emitting rays inspired her to conduct further research. Within a couple months of beginning her research she made two important discoveries that "led her to formulate the theory that the rays were the result of something happening within the atom itself, a property she called radioactivity" (Goldsmith). She discovered that the rays were emitted from the anatomical structure of the atom and the outcome was not due to the interaction of molecules. Pierre Currie later abandoned his own research in crystals to help his wife in testing minerals that revealed high levels of radioactivity. From Marie Curie's testing she concluded that a new more powerful element was responsible for the high levels of radioactivity. The Curies confined their research to the mineral pitchblende because it emitted the strongest rays. They then diligently and progressively separated pitchblende by chemical analysis. They measured the radioactivity of the separate components. "In July, 1898, she and Pierre successfully extracted an element from this ore that was even more radioactive than uranium; they called it polonium in honor of Marie's homeland" (Goldsmith). Within that same years they identified a more radioactive element. This element which was embedded in the pitchblende was named radium. To prove their discovery they needed to isolate a pure form of this element. Which was no easy task, considering that these elements were extremely small and almost unnoticeable. In 1902 they were able to isolate enough radium to confirm its existence. Marie Curie then received a doctorate degree from the Sorbonne University, making it the first awarded to a women in Europe. In 1903 Pierre and Marie Curie and Henri Becquerel where jointly awarded the Nobel Prize in physics for their ... Get more on HelpWriting.net ...
  • 13. Analogy Essay What do Kingda Ka and the discoverer of radioactivity, Marie Curie, have in common? Actually, there is a lot more than you would think. You might say to yourself that they are completely different, which is correct, yet incorrect. One thing is a rollercoaster and the other is a famous scientist, but when you look past just their physical descriptions, you will see how much they actually are alike. They both follow similar paths and they both faced many hardships, but also many great things. Firstly, they both start off slowly. Marie was just an average girl who was born in Poland in 1867. Kingda Ka was just a rollercoaster when construction began. They weren't anything special. Marie grew up like all other girls in Poland did at that... Show more content on Helpwriting.net ... Much like Kingda Ka, Marie was struck down by the fact that after a while, Marie had learned all she could. If she wanted further education, she would have to wait a while to save up enough money to keep going. As they had before, they didn't let this obstacle stop them. Kingda Ka was eventually repaired and it continued working as it had before, even though it had many more light breakdowns than it had before. Marie and her sister had worked out a plan as well. First, they would save up enough money between them to send Marie's sister to college in France first. Then, they would send Marie when they had enough money. Of course, there was a small issue. Since the college was in France, all of the lectures were in French, so Marie would have to learn French in order to understand what was being taught. But this was only a small issue because Marie did know some French, so it was easy for her to learn the rest of the language. But after these early issues, things seemed to be going well. There was nothing major that stopped them. Kingda Ka ran smoothly for quite some time and Marie's interest in science really grew. This part in their lives seemed like the initial hill on Kingda Ka. It was a huge obstacle and it seemed difficult to make it all the way up, but they found a way to make it work. Of course, though, it didn't stay this way. Marie was a very intelligent person.

Rutherford first, bombarded gold foil in particles from a radioactive source. Rutherford saw that some of the particles seeming through the gold foil. Rutherford concluded that matter was made up of empty space, but there was also a small dense portion of matter that deflected the particles. He defined this dense area as being a nucleus. Through this finding, we were able to find discoveries that lead to the discovery of radioactivity. Some people argue that radioactivity should not be used at all mainly because it harms people and fatal, while others say that it should be used for weapons in a war. From the two atomic bombs dropped on Japan in 1945 the effect of radioactivity waves are clear. The effects of radioactivity are not always through a nuclear bomb. Radioactive waves are transmitted through the sun and cosmic radiation. This simply means that people at higher elevations such as the Rocky Mountains and the Colorado mountains are more expose to radioactive waves compared to people that live on or at sea level.

Some forms of radiation can be man–made or found naturally, but both are pretty harmful. When radiation merges with molecules in living cells, it can severely damage them. This cell may become cancerous if the DNA has been damaged. This will mean that it can't repair itself. The cell will go out of control, causing serious health issues, meaning it can increase the risk of both animals and to ourselves in getting cancer. Although radiation is harmful to living cells, too much of it being merged into a living cell will more likely die completely. Sunlight, which is one of the most essential forms of radiation can be extremely harmful in large quantities. Overall, radioactivity has both positive and negative effects on people and the environment. Radioactivity is used in modern day medical equipment and radiotherapy.

  • 20. Should Yucca Mountain Be A Nuclear Waste Disposal Site? Introduction: The task we are in charge with is determining if Yucca Mountain is a suitable long term nuclear waste disposal site, if it is a suitable short term nuclear waste site until other sites are found or other scientific ways to dispose of the waste are found, and lastly if Yucca Mountain is not determined to be a long or short term option for nuclear waste disposal. Option one would be to go ahead with the Yucca Mountain plan of long term storage since it is the only answer we have currently for nuclear waste. Option two would be to use Yucca Mountain as a short term storage unit until we find another more stable site or if we find a way to deactivate the radioactivity in the waste. The last option is to not use Yucca Mountain as a short or long term storage unit because the site is shown to have water leakage and would therefore contaminate the surrounding area. Option One: In 1987 Congress amended the Nuclear Waste Policy Act (NWPA) which made the department of energy (DOE) responsible for investigation and determination of the Yucca Mountain site. For more than twenty years the DOE has investigated and come up with preliminary designs for the mountain.

The alpha particles have an atomic mass of 4 and a charge of +2. When an alpha particle is released from the nucleus, the mass number of the particle decreases by four units and the atomic number decreases by two units. An example of this would be where the helium nucleus is the alpha particle. The energy is a collection of stable nucleons, and those heavier nuclei that can be perceived as collections of alpha particles, such as carbon–12.01 or oxygen–16.00 are also stable. Beta radiation is a stream of electrons that are called beta particles. When the beta particle is released, a neutron is transformed to a proton in the nucleus, thus maintaining the mass number of the nucleus. Although, the atomic number increases by one unit. An example of this occurring is when the electron is the beta particle. Pursuing this further, gamma rays are high–energy photons with a very short wavelength of 0.0005 to 0.1 nm.

  • 32. The Pros And Cons Of Radioactivity Radioactivity has been around since the 1800s. It is very popular in the medical field. It is used my many professionals to help diagnose and treat people every single day. Although it does have some advantages and disadvantages, people still use it to this day. Radioactivity is defined as "the spontaneous emission of particles". (Nuclear Energy). Radioactivity is caused by an unbalanced nucleus in the cell. This happens because there is either an uneven number of protons and/or neutrons. When this happens, the element is considered to have multiple isotopes. Anisotope is an atom with the same number of protons but a different number of neutrons. Thus, they have different atomic weights. This is important to know because there is a such thing as a radioactive isotope. These elements just have additional energy, and they release radiation in different forms. "There are over 800 radioactive isotopes, some of which are natural and some synthetic." (Helmenstine). Radioactive elements can be both artificial and natural. However, in medicine, most of them are more than likely synthetic, since they are the most popular types. The use of radioactive elements in medicine is still growing to this day. Many oncologists use it to treat their patients who have cancer. Many cancer patients use this option. They use the radiation to kill off cancer cells. X–ray technicians or radiologists will also use it to administer x–rays to people who may have a broken bone, or need an MRI. The patient is injected with a radioactive material that helps the doctor be able to see inside the body better, whether it be with pictures or ultrasound.

  • 35. Marie Curie Research Paper Marie Curie Biography On November 7, 1867, Maria Sklodowska was born in Warsaw, Poland during a time of confusion and chaos in Europe. At the time, Warsaw was controlled by a czar, who wanted to eliminate all Polish nationalism by keeping the people away from their cultural traditions. In response to this hypocrisy, Polish rebels ignored their Russian leader and continued with their traditions, which, in the long run, caused major chaos to take form in Poland. Maria's parents, who were professors that feared matters would worsen, focused on educating their daughter in hopes of keeping her away from the problems in Warsaw. Their teachings allowed Maria to comprehend the lessons at a much quicker pace than most other children her age; therefore, ... Show more content on Helpwriting.net ... Her work ethic included late nights with her studies as well as providing help to her younger siblings with their school work. The homework seemed effortless to her, even if challenged or when trying times became a road block in the way of her success; however, some of life's challenges are known to have affected even the talented. During a three year time period, Maria and her family had lost her older sister and her mother to tuberculosis, which caused them to fall into a state of depression. Maria suffered from fatigue, anxiety, and nervous twitches, all of which severely impacted her academics. One day, however, her father decided to send her to her cousin's house in hopes that she would relieve some stress and perhaps become herself again. Once there, Maria began to open her eyes and realized that Warsaw's situation had worsened and her future was unknown. After she returned from her cousin's house, she immediately wanted to go to college to earn an advanced degree, especially since she came home to an unemployed father. However, the problem Maria faced was that the University of Warsaw, the school that she had wanted to attend, only accepted male students. She did not let that deter her. Maria and her sister attended the Floating University, which was an illegal night school that met in various locations in order to avoid being caught by the czar. While having attended the University, she gained more knowledge in the new developments within the scientific ... Get more on HelpWriting.net ...
  • 36. Environmental Pollution: What Are The Problems With... What are the problems with America currently today? One problem we have faced in America is environmental pollutions. Environmental pollutions are the harmful filth in the air, we breathe everyday. Perhaps we do not notice them as we breathe. Some filth is seen from a far distance. Factory filth is the main pollution producer in the USA now. One environmental pollution are caused by factories because the product they produce causes the filth out of them. This could be the car production or agricultural production. America produces a lot of cars for all the people to drive. More cars makes more carbon dioxide (filth) which causes deaths, health problems and global warming. Perhaps we can switch to a different energy source to power these vehicles. ...

  • 37. The Natural Radioactivity Of Soil Samples Abstract The concentrations of 226Ra, 232Th and 40K are measured in the material collected from two locations. The collected materials are tested using gamma ray spectrometry. The activity concentration of the naturally occurring radionuclides 226Ra, 232Th and 40K in building material it varies from 12.6 to 121.4, 13.6 to 142 and from 69.5 to 620.6 Bqkg_1, respectively. The radium equivalent activity, the absorbed dose rate, annual effective dose and hazard index is also calculated Keywords Radionuclides, radiological hazard, building material radioactive 1. Introduction Natural sources exist in several geological formations such as soils, rocks, sediments, vegetation, water and air emit radiation. While 4% is of artificial origin (Chougan–kar et al., 2003; El–Daly and Hussein, 2008) [1]. The natural radioactivity of soil samples determined from the 226Ra, 232Th and40K contents. Rocks and soils contribute considerably to indoor and outdoor exposure to the environmental radioactivity by gamma radiation emitting mainly from 226Ra, 232Th and 40K contents, and beta radiation. The soil radioactivity is a good indicator of the distribution and accumulation of radioactivity in the environment and knowledge of these concentrations provides useful information in the monitoring of environment radioactivity (kessaratikoon and Awaekechi, 2008) [2]. Even though these radionuclides are extensively distributed, their concentrations have been proven to depend on the local geological ... Get more on HelpWriting.net ...
  • 38. The Discovery Of Roentgen Rays And Radioactivity INTRODUCTION AND HISTORY Radiation has been an ever present ingredient in the evolution of life on the Earth. It is not something new, invented by the ingenuity of man in the technological age, it has always been there. INTRODUCTION AND HISTORICAL PERSPECTIVE OF RADIATION THERAPY THE DISCOVERY OF ROENTGEN RAYS AND RADIOACTIVITY On Friday, November 8, 1895, while passing an electric current through a Hittorf–Crookes high– vacuum tube, Wilhelm Conrad Roentgen noticed a light coming from a workbench about a yard away. He identified the shining object as a piece of paper painted with barium platinocyanide. He realized that this light must be caused by a new kind of ray, which he called x– rays and which later became known as roentgen rays. He continued investigation of these rays and found that when he replaced the fluorescent screen with a photographic plate, he could obtain pictures. The most dramatic was one showing the bones in his wife's Bertha Roentgen hand, which was taken on December 22, 1895. X–ray image of Bertha Roentgen's Left Hand Wilhelm Roentgen (1845–1923) On December 28, 1895, Roentgen delivered a written presentation of his discovery to the Physical – Medical Society of Wurzburg.

  • 39. Why Do Nuclear Power Plants Go Wrong From an environmental standpoint nuclear power plants are extremely clean when it comes to electrical power generation. However, there are a lot of ways where nuclear power plants can go wrong. Improperly functioning a nuclear power plant can create problematic situations. Take the Chernobyl disaster for instance, because of their poorly designed nuclear power plant it released tons of radioactivity which scattered across the atmosphere. This resulted in everyone leaving the city. Another recent incident was in Fukushima (Japan), a tsunami hit the nuclear power plants which caused the tins to break and release radioactivity as well. Still to this day there is radioactive dust scattered all over the ground. Moreover, mining and purifying uranium ... Get more on HelpWriting.net ...
