Nuclear energy was discovered through experiments creating the atomic bomb. The first nuclear reactor was created in 1942 at the University of Chicago. Nuclear energy provides a new source of energy through fission or fusion but also poses dangers from radiation. While it has advantages as a clean energy source, nuclear power presents environmental and safety risks such as nuclear waste disposal and potential disasters. There is ongoing debate about the use of nuclear power weighing its benefits against the threats from radiation.
There is increased use of nuclear energy after the Second World War which results in increase in artificial radioactivity on our planet. The objective of this article is to show the estimated amount of artificial radioactivity on earth surface and its effect by comparing it with the radioactive decay which took place in Hiroshima bombing by ‘little boy’. There is estimated amount of 100 trillion curie of radioactivity on earth surface for human use. This man made radioactivity on earth surface has capacity to change temperature of the earth by 0.97oC if heat is evenly distributed and unfortunately Hiroshima bombing did not stop but continued at rate of 39 ‘little boy’ bombing of the earth per second. Every second 39 atomic bombs of ‘little boy’ size are dropped. One can see the large amount of bombing taking place on the earth by artificial radioactivity and the bombing should be stopped and further analysis of artificial radioactivity should also be done
The document critiques Andrew Kenny's argument that nuclear power is a better option than renewable energy. It argues that Kenny exaggerates claims about nuclear power's safety and sustainability. While Kenny provides some valid points about nuclear power's reliability, he underestimates its negative consequences, such as radiation exposure from accidents and the uneven global distribution of uranium resources. The document concludes that Kenny's defense of nuclear power is imbalanced and exaggerated.
This document provides an overview of the history of life on Earth from its beginnings over 4.5 billion years ago to the present. It describes how the early Earth formed and cooled, allowing for the emergence of the first life forms like bacteria in the Precambrian era. The Cambrian explosion saw the first major diversification of multicellular life, including in the seas. Subsequent eras like the Paleozoic, Mesozoic, and Cenozoic witnessed further evolution and radiation of life on land and sea, including plants, insects, dinosaurs, mammals, and eventually humans. Mass extinctions periodically wiped out much life, paving the way for new species to evolve and fill ecological niches.

Climate Change: The Evidence and Our Optionsokiregional
This document summarizes the research of the Ice Core Paleoclimate Research Group at Ohio State University. The group studies ice cores from around the world to understand past climate changes. It receives funding from various organizations. Ice cores provide evidence that some glaciers are currently smaller than they have been in the past 6,000 years and that recent warming is unprecedented over the last 1,000 years. The document discusses both natural and human factors that influence the climate and presents evidence that recent warming is not caused by changes in the sun's output but rather by increasing greenhouse gases from human activities.
The document discusses arguments for and against the origins of life from a naturalistic perspective versus special creation. It covers topics like the Miller-Urey experiment on the formation of amino acids, objections to the conclusions drawn from that experiment, the improbability of life arising from random processes, and experiments by Redi and Pasteur disproving the theory of spontaneous generation. The overall discussion centers around whether life could reasonably be explained through natural processes and evolution or requires an intelligent cause.
Disasters are more natural than man made. The slides talk about pre historic times and the disasters or 5 mass extinctions that took place before the arrival of humans
The document discusses two articles that debate whether nuclear energy should be used as an energy source in the US. The first article, by Rebecca Solnit, argues against nuclear power, claiming it is dangerous and catastrophic to the environment. The second article, by Patrick Moore, addresses common arguments against nuclear power and shows why they lack evidence, arguing that modern nuclear energy is safe and reduces emissions. The document concludes that Moore's article is more persuasive because it uses facts calmly rather than emotion, and does not attack other views.
The document summarizes the 1990 Nobel Prize winners. Elias James Corey won the Nobel Prize in Chemistry for developing the theory and methodology of organic synthesis. Jerome I. Friedman, Henry W. Kendall, and Richard E. Taylor won the Nobel Prize in Physics for their investigations into deep scattering of electrons on protons and neutrons, which supported the quark model in particle physics. Joseph E. Murray and E. Donnall Thomas won the Nobel Prize in Physiology or Medicine for their discoveries regarding organ and cell transplantation, which have benefited patients in need of organ transplants.

Carbon cycle and global concerns on environmentRajat Nainwal
Carbon is the primary building block of life and cycles through different carbon pools in the biosphere, lithosphere, hydrosphere, and atmosphere. The global carbon cycle involves fluxes of carbon between these pools through natural processes like photosynthesis, respiration, and geological processes. However, human activities like burning fossil fuels and deforestation have significantly increased carbon dioxide levels in the atmosphere, disrupting the natural carbon cycle and causing global climate change. Rising global temperatures will lead to problems like rising sea levels, food shortages, and threats to biodiversity.
10 science questions every high school graduate should knowkhartikhan moorthy
A science reporter tested high school students with a 10 question science quiz developed by leading scientists. The quiz covered topics like the percentage of Earth covered by water, how the brain communicates, whether dinosaurs and humans coexisted, Darwin's theory of evolution, why a year is 365 days and a day is 24 hours, why the sky is blue, what causes rainbows, why diseases are hard to treat, the age of the oldest fossils, and why we put salt on sidewalks when it snows. Most students answered the questions correctly except for the question about putting salt on sidewalks to prevent freezing, which stumped most students.
The document discusses how humans have altered the global carbon cycle through burning fossil fuels, deforestation, and burning trees. Burning fossil fuels increases the rate of carbon moving from rocks to the atmosphere. Deforestation and burning trees decreases the rate of carbon moving from the atmosphere to living organisms. This has increased the level of carbon dioxide in the atmosphere, which is a greenhouse gas that absorbs and reradiates infrared radiation, contributing to global climate change. The Mauna Loa curve shows increasing carbon dioxide levels in the atmosphere since the 1950s.

The document argues that nuclear energy should not be relied upon as it accounts for a large portion of U.S. emissions and damages the environment. Switching to renewable resources could drop pollution by over 30% and production costs by over 50%, providing cleaner and cheaper alternatives. Removing nuclear power in favor of renewable energy would benefit the environment through fewer emissions, provide cost-effective power, and increase public safety by reducing vulnerabilities.
Nuclear energy can be produced through two main methods: nuclear fission and nuclear fusion. Nuclear fission involves splitting uranium atoms and was used to power early nuclear reactors and create atomic bombs. Nuclear fusion involves fusing hydrogen atoms and is how energy is generated in stars. While nuclear energy produces little greenhouse gas emissions, it also produces radioactive waste that remains dangerous for thousands of years and accidents can cause radiation poisoning. There are also concerns about the large amounts of water used in uranium mining and current lack of long-term storage for nuclear waste. Alternatives to nuclear energy include wind, water, solar and biomass.

1. Nuclear Radiation
Viktor Chernobay Biology 115
Nuclear energy was discovered in the process of creating the atomic bomb. After
scientists conducted more experiments, they found that nuclear power was a clean and
efficient way to produce energy. “The first nuclear reactor was created on December 2, 1942,
at the University of Chicago by Enrico Fermi.” (Editors of Scientific America, 1995). The
discovery of nuclear energy provided a new source of energy and an alternative to the use of
natural resources: such as coal, oil, water, and wood. At the same time, nuclear energy could
be used in a destructive way, such as the atomic bomb.
At that time, the discovery of a new source of energy was a very significant event. By
using a small amount of plutonium and uranium, two radioactive elements, an enormous
amount of energy could be obtained. Nuclear energy can be produced in two different ways,
by the fission or fusion process. Fission involves the breaking up of heavier atoms into
lighter atoms. In a nuclear fission reaction, two smaller nuclei of approximately equal mass
are formed from the splitting of a large nucleus. This splitting of an atom produces a large
amount of energy. This process is the most common form of nuclear power. Fusion is a
method that combines lighter atoms into heavier atoms. In a nuclear fusion reaction, a large
nucleus is formed from two small nuclei joined together. Fusion reactions are difficult to
produce because of the repulsion of the atom’s negatively charged electron clouds and the
positively charged nucleus. (LeMay, Beall, Robblee, Brower, 1996). Fusion is mostly used
to create the hydrogen bomb. (The World Book Encyclopedia, 1990). The byproduct of
nuclear energy is radiation. Radiation is created from the particles (strontium-90, cesium-
137, radon-222, krypton-85, and nitrogen-16) that are given off as a result of the splitting of
atoms. (Gale Encyclopedia of Science, 1996) (Demmin, 1994).

2. As time went on, the attitudes of people towards nuclear energy changed. There were
many positive and negative aspects for the use of nuclear power. Recently, people worldwide
have started questioning the continued use of nuclear power. Due to the deaths resulting from
the 1986 Chernobyl nuclear reactor accident, as well as the adverse effect the aftermath of
the accident had on the environment, there has been a public outcry concerning the safety of
society. As with many controversial issues, this topic has been widely debated, but a solution
has not been determined.
The positive aspects of the use of nuclear energy are that the supply of natural resources
does not have to be depleted, and also it is clean. It takes a great amount of natural resources
to create a small amount of energy. On the other hand, a very small amount of plutonium and
uranium is necessary for the creation of a large amount of nuclear energy. This is important
since there are relatively small amounts of plutonium and uranium in the earth’s crust.
Compared to the production of power using coal, the creation of power generated by nuclear
energy does not pollute the air. As coal burns, there are poisonous fumes that could cause
sickness, if the area is not properly ventilated. As the cost of electricity rose, the government
was forced to look for an alternative source of energy, which they discovered in nuclear
reactors.
One of the major disadvantages of a reactor is the disposal of the nuclear waste which
harms the environment. “There are 434 nuclear reactors in the world and 110 of them are in
the United States.” (Wasserman, 1996) Not a single one is functioning without polluting the
environment. Attempts to store nuclear wastes have not been very successful. One such
attempt is to bury the nuclear waste underground, but the leakage of nuclear waste has
poisoned the groundwater. Another attempt is to put the nuclear waste into deep ocean water.
Later, this was rejected by the public and also, in violation of an international treaty because
2
3. of the possibility of harming the ocean. Another problem to the environment is the leakage
of radioactive waste from space. This problem is not pollution to the earth’s environment,
but pollution of space. There is no way to dispose of the nuclear waste in space.
The most significant drawback on this controversial issue is the threat of a disaster. The
two most serious situations were the accident at Chernobyl and the explosion of the hydrogen
bomb on Hiroshima. The first time that people discovered the dangers of nuclear power was
when the atomic bomb was dropped, August 6, 1945, on Hiroshima. The effects of the bomb
was that it destroyed 4.7 square miles of the city. Approximately 70,000 people were killed
and about another 70,0000 people were injured. Many people died later as a result of nuclear
radiation and radiation sickness. (The World Book Encyclopedia, 1990). The most serious
nuclear disaster was the Chernobyl accident that occurred April 26, 1986 in the Soviet
Union. (Medvedev, pp.83-89.). An accurate number of deaths as a result of this accident is
very hard to determine due to the secrecy of the U.S.S.R. surrounding this accident.
(Marples, 1996). A study done by a team of scientists from both the United States and Japan
has shown that there has not been any evidence found of genetic mutation, which are changes
in heredity, in the children of the survivors of the bombing of Hiroshima. (Science News,
1996).
Following the Chernobyl accident, Soviet scientists suggest that there is evidence that
radiation has exhibited genetic mutation in the parents who were exposed to radiation.
According to them, the mutation was found in sperm and egg cells, which contain the genetic
building blocks of future generations. The child’s DNA is a combination from both parents’
genetic makeup. When there is any sequence that the child has, but that sequence was not
found in either parent, then this is called germline mutation. Ten years after the accident that
occurred at Chernobyl, evidence of mutation, in the exposed areas of the country, indicates
3
4. that radiation changed genetic makeup and that this has passed onto future generations.
(Science News, 1996). Also, there has been an explosive increase in childhood thyroid
cancer in Belarus, Ukraine and the Russian Federation since 1986. This cancer is present in
brothers and sisters of the same family, which indicates that the cancer is a result of the
accident at Chernobyl. (Balter, 1995).
Whether the atom is used for peace or for war, man must contend with the hazards of
nuclear radiation. This radiation may cause burns, diseases, and death. It may harm future
generations by causing mutations.
In peacetime, the escape of radioactive particles from nuclear plants is the main radiation
hazard. More nuclear power plants will be built if a significant amount of the world’s power
is to come from uranium. As a result of these plants, huge amounts of radioactive material
will be produced. The power plants must take necessary precautions to insure the
communities are safe from the radiation that may escape.
In wartime, the most serious danger from radiation is near or below the place where the
atomic bomb has exploded. If people are not killed by the bomb, then they have to deal with
the radioactive fallout. Even at a distance from the blast, the injury can be serious.
The use of radiation has many positive attributes, but at the same time, the significance of
the drawbacks are overwhelming. No government nor scientist can guarantee the safety of
nuclear plants. Without this guarantee, there is an immediate concern for the welfare of the
world. I believe countries around the world should begin a gradual process of shutting down
nuclear plants and begin making a much greater effort to develop widespread use of other
sources of energy, such as wind and solar power.
In the last decade, public concern for the use of nuclear energy has increased dramatically.
Few can debate that nuclear energy is clean, and can be produced without using hardly any
4
5. natural resources. Likewise, few can debate that radiation is harmful to the environment,
unsafe, and a great danger for all living things. Scientists and mankind have to weigh the
positive as well as the negative aspects of nuclear radiation, and then decide what source of
energy the future holds that will benefit not only all living things, but also the environment.
