The Nuclear Of Uranium And The Atomic Bomb
Introduction
Beginning in 1941 the exploration of uranium 235 and the atomic bomb began. The bomb would be
used against Japan to end the deadly encounters during World War II in exchange for unconditional
surrender. In 1945 the bomb was dropped on Hiroshima killing over 190,000 people and then
another bomb was dropped on Nagasaki killing about 70,000 people. Japan surrendered bringing an
end to the war but this was only the beginning of what is known as the nuclear age.
Historical context
German physicist, Otto Hahn and German chemist, Fritz Strassmann, began conducting experiments
on uranium when, in 1938, the two were completely bewildered by the results of their experiment
and sent the outcome to physicist Lise Meitner who was astounded by the results as well. Otto
Hahn, Fritz Strassmann, and Lise Meitner had become the first to recognize that uranium could split
and release energy. ("Harnessing of Nuclear Fission.") Soon after though, the war started.
World War 2 was started September 1, 1939 by Adolf Hitler and lasted until September 2, 1945. It
was the most widespread and deadliest war in history involving over 30 countries and resulting in
about 50 million deaths. The major aggressors were Germany, Italy, and Japan. 6 million of the
people killed were in concentration camps because they were Jewish. ("World War II History")
During the war Germany took over a small town, St. Joachimsthal in Bohemia that contained a
uranium mine. Physicists Leo

Uranium Mining in Australia Essay
To what extent should there be limitation on the mining of uranium in Australia ?
Uranium has become a big issue as an alternative energy resource in the future due to the shortage
of fossil fuel as a primary energy resource in the world. Australia is one of country that has the
largest uranium deposits in the globe. So, Australia has important opportunity to make a lot of
money from uranium exports to other countries. However, the Australian Government is still
debating this issue because of the negative impact of uranium mining and exploration. For these
reason, some people believe that uranium mining has more positive impacts on the economy such
as, income benefits from uranium exports and an increase a new job opportunities. However, ...

They also point out that the industry has forty per cent of the world uranium reserves. Based on that
reasons, the uranium industry in Australia could make a big profit from export of uranium if the
government takes it seriously. Also, they should be good regulation for uranium trading such as
local trading and international trading. So, some people think that there should not be limitations on
mining of uranium. Another argument against the limitations on uranium mining in Australia is that
uranium mining can increase job opportunities to local people in Australia. According to Greenpeace
Australia Pacific (2006), the uranium industry could create a large number of job opportunities
because this industry needs a lot of employees to support this industry. If the Australian Government
expands its uranium mining, it will create potential local jobs and it would be one solution to solve
the unemployment problem. So, some people believe that the limitation of uranium mining is not
necessary because it can reduce job opportunities in Australia. These economic concerns are
important in the uranium mining debate because the Australian Government can make huge profits
from that industry and solve the unemployment problem as well. However, there are some important
aspects that must be considered such as, uranium as the main material for nuclear weapons, nuclear
power is not efficient or effective, and there is harmful radiation from the mining of uranium. The

The Impact Of Depleted Uranium Against The Federal...
Abstract
The impact of the use of depleted uranium against the Federal Republic of Yugoslavia between 24
March and 5 June 1999 created seriously devastating effects not only on the country of Yugoslavia
but also numerous neighboring countries. The purpose of this paper is to inform the readers of the
detrimental effects of the use of DU on the environment, the impact of the health and quality of life
of the populations affected, a possible contributor to what is referred to as Gulf War Syndrome in
military personnel, and the flagrant violation of the international legal rules (Articles 55 and 56 of
Protocol I (1977) to the Geneva Convention of 1949). There is also suspicion of a conspiracy by the
United Nations with regards to the use of these highly radioactive weapons to cover up their use.

It is radioactive and poisonous and is so dense that when turned into a metal alloy, it can greatly
increase the power of a shell to penetrate armor. When the DU shell hits metal armor, it starts to
burn and releases tiny particles of the radioactive metal into the air. ( Catalinotto, n.d.). In high–
temperature explosions, uranium combustion releases fine particles of uranium oxide, which is
responsible for severely affecting respiratory organs of people within 300m of the explosion.

The Effects Of Uranium On Society
This semester in ENGL 112, I chose to researcher the effects of uranium. I chose this topic because I
learned about the element earlier in the year while sitting in Physics class. Uranium is a very
interesting element that has been applied to many applications in today's world. While in Physics,
the class even had a debate on whether uranium has affected society for the better or for the worse.
My side in the debate was that uranium has affected society for the worse. Uranium has created
many bad problems for the world, and it could potentially create more problems. Uranium is a
radioactive element that is the only metal on Earth that breaks down and creates new elements.
Before the element was discovered, it affected humans while they were mining for stone. Some of
the stone was even used to build schools and homes. The radiation then affected the families and
children throughout their lives without them even knowing it. I feel that I did very well with the

Uranium Vs Plutonium Research Paper
They have always used Uranium and Plutonium isotopes in nuclear power plants to create energy.
These isotopes have lots of hazards however. For example, they run the risk of having a nuclear
meltdown. There is another type of nuclear power that is a lot less risky and it is called Thorium.
Not only is thorium less risky, it is also more abundant in nature than Uranium. They were testing
Thorium at the next generation nuclear power plant I was working at. You might be asking, if it is
more abundant and less risky, why are they just now using it? The idea for using thorium has been
around since 1960. In 1973, they were proposals for research in the United States. These proposals

These control rods are not guaranteed to work. They can be affected in a reactor error. That is why
older reactors could overheat and lose control causing an accident. A thorium reactor can be
instantly shut down by turning off the stream of neutrons. Shutting down the cycle means stopping
the breeding of Th–232 into U–233. This will keep things from getting any more out of hand. Also,
the thorium reactors can be created to function in a liquid state while the uranium and plutonium
reactors cannot. When the older reactors were heading towards a meltdown, there was no way to
stop the fission reactions. A thorium reactor design called LFTR has a "plug" at the bottom of the
reactor that melts if the temperature of the reacting fuel gets too high. If this were to happen, all the
hot liquid would fall into a container and the reaction will stop. That keeps things from getting out

The main effect associated with exposure to uranium is kidney toxicity. It can be caused by
breathing air containing uranium dusts or by eating substances containing uranium, which then
enters the bloodstream. Once in the bloodstream, the uranium compounds are filtered by the
kidneys, where they can cause damage to the kidney cells.
The extent of damage for exposure to a uranium compound depends on how the substance is
exposed. In most cases, only inhalation and ingestion can really have an effect on the body, and
although absorption of some some soluble compounds through the skin is possible, such exposure
are generally not significant.
Several possible health effects are associated with human exposure to radiation from uranium. All

Navajo People: Health Effects of Uranium Mining
The growing demand for consumer goods, such as electricity, fuel for vehicles, plastics and
petrochemical products, etc., threatens the biodiversity. It also threatens the ecosystems and effects
the environmental health. Many Navajo people traveled to mines off the reservation seeking work
and would often move their families with them in mine camps. The mineworkers, the only job that
was available, were paid at an hourly wage was less than a dollar. The jobs included blasters, timber
men, muckers, transporters, and millers. Other health hazards have emerged, in particular uranium
mining. The hazards of uranium mining have caused serious respiratory disease and that other
respiratory illnesses, including silicosis, tuberculosis, pneumonia, and emphysema, were causing
deaths in uranium mineworkers at rates approaching those from lung cancer.
Though, there were more than 1000 abandoned uranium mines are on Navajo Reservation, over 7
million tons of uranium ore were extracted from Navajo lands and approximate 750 mines in

Notes On The Migration Of Uranium
lateritization process leads to the migration of uranium, but the produced laterites of either grey (Al)
or brown (Fe) soils are good adsorbents for uranium and other heavy metals. The karstification
process leads to the formation of caves which are filled by either allochtonous or autochtonous soils.
These karst soils host uranium and rare earth elements (El Aassy et al., 2006).

This is why uranium is so popular within the higher ups of countries, especially the military.
It is not until recently that people have become dependent on this element, and not necessarily for
the good of it, and the world. There is an obsession with uranium because of its unique properties.
Uranium is extremely powerful because of its radioactive properties and unstable nuclei, especially
that of Uranium–235. It is able to break down and release high frequency radiation through alpha
and beta decay. It is because of these characteristics that Uranium has such a craze on the population
of the world (Cox, 1995; Scerri, 2007). The properties of uranium allow people to create powerful
plants to produce electricity, and weapons strong enough to destroy the world.
Nuclear Reactors Nuclear reactors were not originally built for electric purposes. In fact, when these
reactors were first built, their sole purpose was for research, and the creation of the element
plutonium which was to be used in nuclear warfare (Cox, 1995). Thankfully times have changed, to
a certain extent, and the nuclear reactors are used for electrical purposes, and other powering
supplies only (Cox, 1995). Nuclear reactors can be found world–wide especially in France, as well

1.1 Natural Uranium Variations in Geologic Ores Uranium consists of four naturally occurring
isotopes (238U, 235U, 234U, and 236U), with multiple oxidation states. Variations in uranium
isotopics are unique in that both chemical (redox interactions) and nuclear processes (decay and
volume–fractionation) play an important role. Four oxidation states known for uranium ions in
aqueous solutions (+III to +VI) which usually exist as U+3, U+4, UO2+, and UO2+2 [Gindler,
1978]. Under oxidizing conditions, uranium is primarily present in the hexavalent (VI) state, which
can form highly mobile soluble complexes (primarily with carbonates) [Langmuir, 1997]. In a
reducing environment, however, uranium will primarily occur in the tetravalent (IV) state. U+4
tends to form relatively insoluble complexes and has higher sorption kinetics compared to the
hexavalent state [Langmuir, 1997].
With an increase in measurement capabilities, all three isotopic ratios (relative to 238U) have been
shown to naturally vary in some degree due to various factors. The first uranium isotopic that was
discovered to have natural variation was 234U/238U, the increased abundance of 234U in seawater
(~15%) perhaps being the best example [Chen et al., 1986]. Variations in 234U are a consequence of
an increased mobility of 234U relative to other uranium isotopes due to redox interactions.
Production of 234U occurs through α–decay of 238U, which subsequently results

Uranium 235 Neutrons
Uranium 235 (U235) on itself is stable, however if an atom is hit with a neutron, it will absorb that
neutron turning into Uranium 236 (U236), and therefore becomes unstable. It then spontaneously
splits into 2 atoms, krypton 92 and barium 141 molecule. A new nuclei forms when an unstable
nucleus decays creating fission products. Essentially, the fewer neutrons there are loose, the fewer
fissions will occur. It is noticed that both the atoms do no equal up to 236, because in fact, 3
neutrons are dispersed and then further colliding with other Uranium 235 molecules. To further

The Mining Of Uranium Mining
Uranium Mining Uranium ore can be mined underground or open–cut, this is dependent on the
depth, which the uranium is at. In general, open pit mining is used where the deposits are close to
the earth surface, whereas the underground mining is used for deep deposits on average greater than
100 meters deep. Open–pit mining requires the removal of soil and waste rock on top of the ore to
expose the hard rock. Then a pit is dug to access the ore, where the walls of the pit are mined in a
series of benches to prevent them from collapsing. This is also done so that the workers can mine
each bench by drilling holes into the rock and panting explosives, which are detonated to break up
the rock. The broken rock is brought to the surface in a ... Show more content on Helpwriting.net ...
Since the concentration of the uranium mined is very high, the radioactivity is a potential hazard,
hence there are precautions taken during the mining and milling process to protect the health of the
workers. The first and foremost is forced ventilation in the underground mines, to ensure that there
is no radioactive particle being breathed in. Efficient dust control as the dust may contain
radioactive particles and emit radon gas. Keeping workers safe by setting a limit to the radiation
exposure in mines and mills as well as routine monitoring of air, dust and surface contamination is
undertaken. In Canada, this means that in area of high concentration of uranium, it is mined by

How Should Uranium Be Used In Energy Resources?
Now days' energy is an important issue we need energy to run our houses, to run our transportation
vehicles, factories, etc. also, the resources we rely on are nonrenewable which is a big issue. In this
essay, I, will be discussing uranium as a solution for the energy problem I will talk about uranium,
and the science of uranium, the advantages, the good thing and the disadvantages, the bad things
about using uranium as an energy resource.
Today, humans rely on variety of energy resources to heat homes, propel transportation vehicles, and
produce goods for shelter, food health care, and entertainment. Some of those sources are renewable
like biomass and solar energy, and others are non–renewable like fossil fuels (coal, oil, and natural
gas). as we know most of our electricity comes from fossil fuels which are non–renewable however,

Using uranium–235 the first nuclear fission was discovered. When the nucleus of U–235 atom hit a
moving neutron, it undergoes fission and splits into Barium–141 and krypton 92 and then releases
some energy and heat, also two neutrons hit uranium again so more energy and heat is released .so a
chain reaction is made. After that the energy released from uranium is taken to make nuclear power

energy with the lowest impact on human and ecological health. A number of differing production
methods have been derived in response to this, one of the most controversial of which is Nuclear
energy supplied through Uranium mining. This is a uniquely topical issue in Australia, on account of
the sheer amount of Uranium held in Australia's borders (30% of the world's reserves) and its
potential impact on Australia's economy (4), the politicised and partisan nature of nuclear debate,
along with longstanding opposition associated with such striking international disasters as the
Chernobyl and, more recently, Fukushima events (1). With such significant ... Show more content on

One significant advantage of nuclear energy through the mining of Uranium is its carbon neutral
energy production property (3). However, during a meltdown or another catastrophe, Nuclear
reactors have the capacity to release significant amounts of toxic radioactive isotopes, such as
Strontium 90, Cadmium 113 and Caesium 137, which has the potential to cause significant harm to
health (2) and biodiversity (11). Coal on the other hand is a well–documented releaser of greenhouse
gasses, with one tonne of coal generating 2.6 tonnes of CO2 alone. Globally, this accounts for 6.4
billion tonnes of CO2 per year, with this value progressively increasing (5). Further, the use of coal
in electricity production results in the release of particulates into surrounding areas. Particularly in
third world and developing nations where regulation on pollution is lax, this causes major tangible
health risks to those who live near the plants– a report by the World Health Organisation estimates
that deaths directly related to outdoor pollution from Coal–based electricity generation amounts to
approximately 2 million deaths per year

Chernobyl accident dominates the Energy accidents sub–category, of most disastrous nuclear power
plant accident in history, both in terms of cost and casualties. It is one of only two nuclear energy
accidents classified as a level 7 event (the maximum classification) on the International Nuclear

Three Mile Island Accident. In 1979 Three Mile Island nuclear power plant in Harrisburg,
Pennsylvania, was destroyed because of a cooling malfunction. According to the plant operators
that, "After a radiation leak was discovered on March 30, residents were advised to stay indoors.
Experts were uncertain if the hydrogen bubble would create further meltdown or possibly a giant

Depleted Uranium Research Paper
Depleted uranium is a type of radioactive material that is produced during the Uranium enrichment
process (WHO, N.D., p.1). The enriched uranium is removed from the depleted portions and used
for various purposes such as production of nuclear weapons or nuclear power plants; the depleted
portions are used for, among other things, military munitions. These munitions are not highly
radioactive but could they be used for a RDD?
Depleted uranium is used for military purposes because of its incredible density (HPS, 2010, p.1).
The material is harder than steel and serves as an excellent armor piercing round. The material is not
used for its radiation producing properties or to poison the target. It has been used around the world
for military purposes since before the 1980s. Health risks to soldiers using the depleted uranium
ammunitions are considered low because the round produces very low radiation which is not in
excess of acceptable levels (HPS, 2010, p.2). However depleted uranium can be dangerous in two
ways: if it is embedded in the body or material near the impact site is inhaled. Both ways require
that the material enter the body. This means that residual radiation put off by an RDD explosion
using depleted uranium would not be an issue, just the debris and dust created by the explosion. If a
person inhales the dust or gets a piece of the depleted uranium lodged under the skin the radiation
produced will, over time, lead to significant health effects, most ... Show more content on

Uranium is most notably recognised for its radioactivity however, when compared with other
radioactive elements, Uranium has quite slow rate of decay (Pappas, 2015). U–235, an isotope of

Depleted Uranium Contamination
Depleted Uranium Contamination
From Military Activities
1. Introduction
Depleted uranium (DU, Q–metal, D–depletalloy, or D–38) is uranium with a lower concentration of
the fissible isotope U–235 than natural uranium. Natural uranium consists of 99.28% U–238, 0.71%
U–235, and 0.0054% U–234.1 Nuclear reactors use uranium as their basic fuel in the form of UO2.2
DU is a byproduct from enriching natural UO2 to use in these nuclear power reactors. Uranium
decays slowly by emitting an alpha particle. U–238 has a 4,510,000,000–year half–life and U–235
has a 247,000–year half–life; which means that DU is significantly less radioactive than natural
uranium. Although it also has civilian uses, DU byproduct majorly has military uses.3,4 Properties
that make DU suitable for military weaponry, as a part of kinetic–based armor–piercing shells are its
high density and pyrophoric nature.5

Uranium History and Beginning Risks
Before going straight in on the subject of DU, it would be appropriate to explain it's parent. Uranium
goes back many centuries. According to Briner (2010), Uranium assisted the Germans in the
creation of certain textiles and paint in the 1500s. Miners were needed to retrieve this element and
over time lung cancer set in the miners due to radioactive dust from uranium (p. 304). Later in time,
the United States took interest in uranium. According to Brugge & Goble (2002), it was in 1948 the
uranium mining boom started exposing people to radiation dust leading to lung cancer, similar
situation to Germany.

The Chemical Element Of Uranium
Background
Uranium (U) is a chemical element; it is a silvery–white metal. It is one of the heaviest of all the
naturally – occurring elements. It was discovered in 1789 by Martin Klaproth, it was named after the
planet Uranus, which was discovered eight years earlier. Uranium can be found naturally in small
amounts in rocks, air, soil and water.
PHYSICAL AND CHEMICAL PROPERTIES
Atomic number 92
Atomic mass 238.03 g.mol –1
Density 18.95 g.cm–3 at 20°C
Boiling point 3818 °C
Melting point 1132 °C
Isotopes 11
Electro–Negativity according to Pauling 1.7
Uranium is hard, malleable and ductile. Uranium metal has a very high density. It is very reactive so
cannot be found in the environment in its elemental form. When finely divided, it can react with
cold water. In air it is coated by uranium oxide, tarnishing rapidly. It is attacked by steam and acids.
It has the ability to form solid solutions and inter– metallic compounds with many metals. While
Uranium is not hazardous by itself, some of its by–products and decay products pose a huge threat
upon build–up.
Uranium is weakly radioactive due to its unstable isotopes; again it has gained importance in the
generation of Nuclear energy. It is of great demand in the production of bullets, missiles and bombs.
It is also used to fuel power plants by enriching it with the uranium–235 isotope. The isotope

The Nuclear Of Uranium And The Atomic Bomb

  • 1. The Nuclear Of Uranium And The Atomic Bomb Introduction Beginning in 1941 the exploration of uranium 235 and the atomic bomb began. The bomb would be used against Japan to end the deadly encounters during World War II in exchange for unconditional surrender. In 1945 the bomb was dropped on Hiroshima killing over 190,000 people and then another bomb was dropped on Nagasaki killing about 70,000 people. Japan surrendered bringing an end to the war but this was only the beginning of what is known as the nuclear age. Historical context German physicist, Otto Hahn and German chemist, Fritz Strassmann, began conducting experiments on uranium when, in 1938, the two were completely bewildered by the results of their experiment and sent the outcome to physicist Lise Meitner who was astounded by the results as well. Otto Hahn, Fritz Strassmann, and Lise Meitner had become the first to recognize that uranium could split and release energy. ("Harnessing of Nuclear Fission.") Soon after though, the war started. World War 2 was started September 1, 1939 by Adolf Hitler and lasted until September 2, 1945. It was the most widespread and deadliest war in history involving over 30 countries and resulting in about 50 million deaths. The major aggressors were Germany, Italy, and Japan. 6 million of the people killed were in concentration camps because they were Jewish. ("World War II History") During the war Germany took over a small town, St. Joachimsthal in Bohemia that contained a uranium mine. Physicists Leo ... Get more on HelpWriting.net ...

  • 3. Uranium Mining in Australia Essay To what extent should there be limitation on the mining of uranium in Australia ? Uranium has become a big issue as an alternative energy resource in the future due to the shortage of fossil fuel as a primary energy resource in the world. Australia is one of country that has the largest uranium deposits in the globe. So, Australia has important opportunity to make a lot of money from uranium exports to other countries. However, the Australian Government is still debating this issue because of the negative impact of uranium mining and exploration. For these reason, some people believe that uranium mining has more positive impacts on the economy such as, income benefits from uranium exports and an increase a new job opportunities. However, ... Show more content on Helpwriting.net ... They also point out that the industry has forty per cent of the world uranium reserves. Based on that reasons, the uranium industry in Australia could make a big profit from export of uranium if the government takes it seriously. Also, they should be good regulation for uranium trading such as local trading and international trading. So, some people think that there should not be limitations on mining of uranium. Another argument against the limitations on uranium mining in Australia is that uranium mining can increase job opportunities to local people in Australia. According to Greenpeace Australia Pacific (2006), the uranium industry could create a large number of job opportunities because this industry needs a lot of employees to support this industry. If the Australian Government expands its uranium mining, it will create potential local jobs and it would be one solution to solve the unemployment problem. So, some people believe that the limitation of uranium mining is not necessary because it can reduce job opportunities in Australia. These economic concerns are important in the uranium mining debate because the Australian Government can make huge profits from that industry and solve the unemployment problem as well. However, there are some important aspects that must be considered such as, uranium as the main material for nuclear weapons, nuclear power is not efficient or effective, and there is harmful radiation from the mining of uranium.

Abstract The impact of the use of depleted uranium against the Federal Republic of Yugoslavia between 24 March and 5 June 1999 created seriously devastating effects not only on the country of Yugoslavia but also numerous neighboring countries. The purpose of this paper is to inform the readers of the detrimental effects of the use of DU on the environment, the impact of the health and quality of life of the populations affected, a possible contributor to what is referred to as Gulf War Syndrome in military personnel, and the flagrant violation of the international legal rules (Articles 55 and 56 of Protocol I (1977) to the Geneva Convention of 1949).

  • 9. The Effects Of Uranium On Society This semester in ENGL 112, I chose to researcher the effects of uranium. I chose this topic because I learned about the element earlier in the year while sitting in Physics class. Uranium is a very interesting element that has been applied to many applications in today's world. While in Physics, the class even had a debate on whether uranium has affected society for the better or for the worse. My side in the debate was that uranium has affected society for the worse. Uranium has created many bad problems for the world, and it could potentially create more problems. Uranium is a radioactive element that is the only metal on Earth that breaks down and creates new elements. Before the element was discovered, it affected humans while they were mining for stone. Some of the stone was even used to build schools and homes. The radiation then affected the families and children throughout their lives without them even knowing it. I feel that I did very well with the papers leading up to the Position Paper. In the Research Proposal, I discussed all the information about uranium I knew, such as, Hiroshima and Nagasaki, Chernobyl, nuclear ... Show more content on Helpwriting.net ...

  • 11. Uranium Vs Plutonium Research Paper They have always used Uranium and Plutonium isotopes in nuclear power plants to create energy. These isotopes have lots of hazards however. For example, they run the risk of having a nuclear meltdown. There is another type of nuclear power that is a lot less risky and it is called Thorium. Not only is thorium less risky, it is also more abundant in nature than Uranium. They were testing Thorium at the next generation nuclear power plant I was working at. You might be asking, if it is more abundant and less risky, why are they just now using it? The idea for using thorium has been around since 1960. In 1973, they were proposals for research in the United States. These proposals didn't fall through though and that is because of nuclear weapons. During this time, was the Cold War, and ... Show more content on Helpwriting.net ... These control rods are not guaranteed to work. They can be affected in a reactor error. That is why older reactors could overheat and lose control causing an accident. A thorium reactor can be instantly shut down by turning off the stream of neutrons. Shutting down the cycle means stopping the breeding of Th–232 into U–233. This will keep things from getting any more out of hand. Also, the thorium reactors can be created to function in a liquid state while the uranium and plutonium reactors cannot. When the older reactors were heading towards a meltdown, there was no way to stop the fission reactions. A thorium reactor design called LFTR has a "plug" at the bottom of the reactor that melts if the temperature of the reacting fuel gets too high. If this were to happen, all the hot liquid would fall into a container and the reaction will stop. That keeps things from getting out of control. Thorium has other benefits to.

It can be caused by breathing air containing uranium dusts or by eating substances containing uranium, which then enters the bloodstream. Once in the bloodstream, the uranium compounds are filtered by the kidneys, where they can cause damage to the kidney cells. The extent of damage for exposure to a uranium compound depends on how the substance is exposed. In most cases, only inhalation and ingestion can really have an effect on the body, and although absorption of some some soluble compounds through the skin is possible, such exposure are generally not significant. Several possible health effects are associated with human exposure to radiation from uranium. All uranium isotopes mainly emit alpha particle and so, they have little penetrating ability.

It can deposit in your liver, spleen, and kidneys. This can be caused by breathing in uranium dusts or by eating substances containing the element. Uranium mining is a major occupation where people are dealing with this element in the industry world. Overexposures to this hazard is dealt with when mining. Major mining are done in Australia and Canada, which has been done for over 40 years. Safety regulations today are among the most comprehensive and stringent in the world. It has been reported due to inspections that radiation doses in the mines are well within regulatory limits. In occupational settings, the Occupational Safety and Health Act (OSHA) regulates the limits of worker exposures based on the solubility of the uranium compound. The Department of Energy (DOE) has issued regulations applicable to its facilities that limit environmental discharges and worker exposure to uranium isotopes. OSHA has established the permissible exposure level (PEL) for airborne uranium in the workplace as 0.25 milligrams cubic meter at a time weighted average (TWA) of a 40 – hour workweek. Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) for uranium of 30 micrograms per liter (µg/L) in drinking water.

Navajo People : Health Effects Of Uranium Mining Navajo People: Health Effects of Uranium Mining The growing demand for consumer goods, such as electricity, fuel for vehicles, plastics and petrochemical products, etc., threatens the biodiversity. It also threatens the ecosystems and effects the environmental health. Many Navajo people traveled to mines off the reservation seeking work and would often move their families with them in mine camps. The mineworkers, the only job that was available, were paid at an hourly wage was less than a dollar. The jobs included blasters, timber men, muckers, transporters, and millers. Other health hazards have emerged, in particular uranium mining. The hazards of uranium mining have caused serious respiratory disease and that other respiratory illnesses, including silicosis, tuberculosis, pneumonia, and emphysema, were causing deaths in uranium mineworkers at rates approaching those from lung cancer. Though, there were more than 1000 abandoned uranium mines are on Navajo Reservation, over 7 million tons of uranium ore were extracted from Navajo lands and approximate 750 mines in operation. Uranium has been extracted from open–pits and underground mines. The milling process extracts uranium oxide from ore to form yellowcake, a yellow or brown powder that contains about 90 percent uranium oxide. The total volume of mill tailings generated in the U.S. is over 95 percent of the volume of all radioactive waste from all power production. Uranium is a very heavy metal which can ...

Notes On The Migration Of Uranium lateritization process leads to the migration of uranium, but the produced laterites of either grey (Al) or brown (Fe) soils are good adsorbents for uranium and other heavy metals. The karstification process leads to the formation of caves which are filled by either allochtonous or autochtonous soils. These karst soils host uranium and rare earth elements (El Aassy et al., 2006). (2) Middle Marly Dolostone–Siltstone Member is also karstified and lateritized and consists of marl with siltstone and gibbsite–bearing siltstone (Fig. 5a). Its thickness is 6–9 m and it is moderately radioactive. (3) Upper Dolostone Member unconformably overlies the karstified and lateritized middle member and consists of bedded dolostone with thin shale interbeds (Fig. 5b). The dolostone beds are present as step–like forms and in some parts are not deposited and laterally vary to grey claystone. The dark grey claystone as noticed in the Allouga, Abu Zarab and Abu Hamata localities is enriched in elemental sulphur as an oxidation product of pyrite and chalcopyrite. Its thickness is 3–4 m and the dolostone has low radioactivity, while the dark grey claystone is moderately radioactive.

The United States government holds this form of energy in such high regard that in 2005 the "Energy Policy Act" was placed into effect. This gave certain tax deductions and even government assured loans for nuclear power plants that were built to aid the civilian population. To date there are currently 61 operating nuclear power plants in the US alone, with 450 known power plants operating worldwide and 60 additional plants under construction.

This is why uranium is so popular within the higher ups of countries, especially the military. It is not until recently that people have become dependent on this element, and not necessarily for the good of it, and the world. There is an obsession with uranium because of its unique properties. Uranium is extremely powerful because of its radioactive properties and unstable nuclei, especially that of Uranium–235. It is able to break down and release high frequency radiation through alpha and beta decay. It is because of these characteristics that Uranium has such a craze on the population of the world (Cox, 1995; Scerri, 2007). The properties of uranium allow people to create powerful plants to produce electricity, and weapons strong enough to destroy the world. Nuclear Reactors Nuclear reactors were not originally built for electric purposes. In fact, when these reactors were first built, their sole purpose was for research, and the creation of the element plutonium which was to be used in nuclear warfare (Cox, 1995).

With attention increasing on uranium, specifically the fissile isotope 235, ideas of controlling acquisition was brought forth. It was suggested by scientists of the Manhattan Project that some organized system of control was needed on nuclear technology, including uranium [citation needed]. The Acheson–Lillienthal report (look up report) described the imperfect nature of technology controls, and suggested an approach focused more on material controls [citation needed]. While the current International Atomic Energy Agency (IAEA) safeguards system takes advantage of material controls, accounting ...

Variations in uranium isotopics are unique in that both chemical (redox interactions) and nuclear processes (decay and volume–fractionation) play an important role. Four oxidation states known for uranium ions in aqueous solutions (+III to +VI) which usually exist as U+3, U+4, UO2+, and UO2+2 [Gindler, 1978]. Under oxidizing conditions, uranium is primarily present in the hexavalent (VI) state, which can form highly mobile soluble complexes (primarily with carbonates) [Langmuir, 1997]. In a reducing environment, however, uranium will primarily occur in the tetravalent (IV) state. U+4 tends to form relatively insoluble complexes and has higher sorption kinetics compared to the hexavalent state [Langmuir, 1997]. With an increase in measurement capabilities, all three isotopic ratios (relative to 238U) have been shown to naturally vary in some degree due to various factors. The first uranium isotopic that was discovered to have natural variation was 234U/238U, the increased abundance of 234U in seawater (~15%) perhaps being the best example [Chen et al., 1986]. Variations in 234U are a consequence of an increased mobility of 234U relative to other uranium isotopes due to redox interactions. Production of 234U occurs through α–decay of 238U, which subsequently results ... Get more on HelpWriting.net ...

The production of uranium through hydrometallurgical processes such as leaching, ion exchange, solid–liquid separation and solvent extraction has not been without controversy, especially during the early stages of the industry. Nowadays, the industry has changed drastically and a lot more can be done to ensure that safety is a number one priority. 2 Safety issues The process of mining uranium releases radon into the atmosphere as well as other heavy metals if not properly managed. Radon is a colourless, tasteless gas and exposure to high levels can increase the chances of getting cancer. As a result, every country that has nuclear facilities, has regulations to ensure public land, air and water (both surface and groundwater) are protected now and in the future

Uranium 235 Neutrons Uranium 235 (U235) on itself is stable, however if an atom is hit with a neutron, it will absorb that neutron turning into Uranium 236 (U236), and therefore becomes unstable. It then spontaneously splits into 2 atoms, krypton 92 and barium 141 molecule. A new nuclei forms when an unstable nucleus decays creating fission products. Essentially, the fewer neutrons there are loose, the fewer fissions will occur. It is noticed that both the atoms do no equal up to 236, because in fact, 3 neutrons are dispersed and then further colliding with other Uranium 235 molecules. To further discuss the process of Uranium fission, it can be referred to what is called the Chain Reaction. In the chain reaction mentioned (Fig 1), the neutrons released by the ...

In general, open pit mining is used where the deposits are close to the earth surface, whereas the underground mining is used for deep deposits on average greater than 100 meters deep. Open–pit mining requires the removal of soil and waste rock on top of the ore to expose the hard rock. Then a pit is dug to access the ore, where the walls of the pit are mined in a series of benches to prevent them from collapsing. This is also done so that the workers can mine each bench by drilling holes into the rock and panting explosives, which are detonated to break up the rock. The broken rock is brought to the surface in a ... Show more content on Helpwriting.net ... Since the concentration of the uranium mined is very high, the radioactivity is a potential hazard, hence there are precautions taken during the mining and milling process to protect the health of the workers. The first and foremost is forced ventilation in the underground mines, to ensure that there is no radioactive particle being breathed in. Efficient dust control as the dust may contain radioactive particles and emit radon gas. Keeping workers safe by setting a limit to the radiation exposure in mines and mills as well as routine monitoring of air, dust and surface contamination is undertaken. In Canada, this means that in area of high concentration of uranium, it is mined by remote control technology. Of course, working in a mine, the workers are given the equipment and technology necessary to meet the radioactive conditions. At last, there are designated employees (those that are exposed to uranium) are monitored for radiation contamination as well as personal dosimeters are worn to measure exposure to gamma radiation.

However, during a meltdown or another catastrophe, Nuclear reactors have the capacity to release significant amounts of toxic radioactive isotopes, such as Strontium 90, Cadmium 113 and Caesium 137, which has the potential to cause significant harm to health (2) and biodiversity (11). Coal on the other hand is a well–documented releaser of greenhouse gasses, with one tonne of coal generating 2.6 tonnes of CO2 alone. Globally, this accounts for 6.4 billion tonnes of CO2 per year, with this value progressively increasing (5). Further, the use of coal in electricity production results in the release of particulates into surrounding areas.

  • 52. Depleted Uranium Research Paper Depleted uranium is a type of radioactive material that is produced during the Uranium enrichment process (WHO, N.D., p.1). The enriched uranium is removed from the depleted portions and used for various purposes such as production of nuclear weapons or nuclear power plants; the depleted portions are used for, among other things, military munitions. These munitions are not highly radioactive but could they be used for a RDD? Depleted uranium is used for military purposes because of its incredible density (HPS, 2010, p.1). The material is harder than steel and serves as an excellent armor piercing round. The material is not used for its radiation producing properties or to poison the target. It has been used around the world for military purposes since before the 1980s. Health risks to soldiers using the depleted uranium ammunitions are considered low because the round produces very low radiation which is not in excess of acceptable levels (HPS, 2010, p.2). However depleted uranium can be dangerous in two ways: if it is embedded in the body or material near the impact site is inhaled. Both ways require that the material enter the body. This means that residual radiation put off by an RDD explosion using depleted uranium would not be an issue, just the debris and dust created by the explosion. If a person inhales the dust or gets a piece of the depleted uranium lodged under the skin the radiation produced will, over time, lead to significant health effects, most ...

Introduction Depleted uranium (DU, Q–metal, D–depletalloy, or D–38) is uranium with a lower concentration of the fissible isotope U–235 than natural uranium. Natural uranium consists of 99.28% U–238, 0.71% U–235, and 0.0054% U–234.1 Nuclear reactors use uranium as their basic fuel in the form of UO2.2 DU is a byproduct from enriching natural UO2 to use in these nuclear power reactors. Uranium decays slowly by emitting an alpha particle. U–238 has a 4,510,000,000–year half–life and U–235 has a 247,000–year half–life; which means that DU is significantly less radioactive than natural uranium. Although it also has civilian uses, DU byproduct majorly has military uses.3,4 Properties that make DU suitable for military weaponry, as a part of kinetic–based armor–piercing shells are its high density and pyrophoric nature.5 It wasn't until the 1970's the Pentagon began searching for material to make denser armor–piercing projectiles that DU started being used in conflicts.
