Nuclear radiation research papers

Sample Research Papers Nuclear energy is a comparatively new source of energy. The first nuclear power plant was commissioned in June in Obninsk, Russia. Fossil fuels offer a limited source of energy, as they are non-renewable. Eventually these supplies will cease, this is predicted to be in the next few decades.

An estimate based on fuel consumption in America, predicts as early as there will be no fossil fuels left.

Research Papers It has been pointed out that the soil is contaminated by radioactive materials emitted It has been pointed out that the soil is contaminated by radioactive materials emitted from reactor 1 of the FDNPP by the accident that occurred in March,

The energy used by the whole world is approximated to be the coal equivalent to Gigatons per year. Fossil fuels reserves total for the world in had approximately Gigatons of coal and This is why extensive research has gone into looking for new sources of energy to keep things powered.

Energy sources currently being used are hydroelectricity, wind turbines, solar power, fossil fuels and nuclear power, and now also hydrogen fuel cells.

There is much controversy over the health and safety issues of using nuclear power, especially after Three Mile Island and the Chernobyl disasters. Where does the energy come from? Nuclear fission The nucleus is the centre of the atom which is normally made up of the same number of protons as it has neutrons.

However, some very large nuclei in certain isotopes have an imbalance.

ABOUT THE MAGAZINE

They can often be found with too many neutrons, and this imbalance will result in the nucleus becoming unstable. Uranium is a radioactive substance which due to its large size and unstable state can undergo induced fission. Its nucleus can be split into smaller atoms when induced by a neutron. This process will release two or three neutrons, depending on how the atom splits.

These new neutrons can then initiate the decomposition of the nuclei of other atoms of Uranium. Propagation by the chain reaction releases more neutrons and causes further nuclear splits. Under controlled conditions, the rate of this chain reaction can be kept at a constant rate.

This produces high temperatures but is not allowed to react out of control as in a nuclear bomb. The heat produced is used to turn water into steam, the steam then turns a turbine and generator, creating electricity.

Therefore it is necessary to enrich natural Uranium to use for nuclear power.

Units of radiation and radioactivity

This is done by converting uranium oxide extracted from ore into gaseous form, uranium hexafluoride. From this form it can be enriched from its natural proportion of 0. A higher enrichment means better efficiency, and ordinary water can then be used as a moderator.

The form of uranium usually used is pellet form, these are arranged into rods and then to bundles. These bundles are surrounded by a moderator such as water, graphite or heavy water. The moderator slows down the emitted neutrons by reducing their energy as they collide with the nuclei of the moderator.Nuclear Energy: the Good, the Bad, and the Debatable Learn more about nuclear technology, its benfits, and its dangers.

and can be stopped by a single sheet of paper. However, if these particles do manage to come into contact with unprotected, internal cells, by ingestion for When it comes to nuclear radiation, there is also a health. THE NEGATIVE PHYSICAL EFFECTS OF NUCLEAR RADIATION Page 1 Abstract Nuclear radiation has been a major problem since when the Second World War began.

A major contribution to World War Two is the nuclear bomb, also known as the Atom bomb. Once the two bombs were dropped, the usually terminal Leukemia was derived throughout Japan.

People who survive a nuclear blast may be exposed to radioactive ash and dust called fallout. Finding a good shelter as soon as possible and going inside is critical to surviving fallout.

A. The Nuclear Regulatory Commission, protecting people and the environment. - The Different Types of Radiation There are four types radiation: alpha radiation, beta radiation, and gamma radiation. Neutron radiation is also encountered in nuclear power plants and high-altitude flight and emitted from some industrial radioactive sources.
