Which in fact are four things that occur the least in the nuclear power field. Additional radioactive isotopes are produced during this process. The energy released during a nuclear explosion, which comes from energy released from electron shells around the nuclei, can be more than 1 million times greater than that of a conventional explosion. Short essay on Nuclear hazards. Radioactivity is the phenomenon of emission of energy from radioactive isotopes (i.e., unstable isotopes), such as Carbon-14, Uranium-235, Uranium-238, Uranium-239, Radium-226, etc. <> Nuclear Hazard means any nuclear reaction, radiation or radioactive contamination, all whether controlled or uncontrolled of however caused or any consequence of any of them.Loss caused by the nuclear hazard shall not be considered loss caused by fire, explosion, or smoke, whether these perils are specifically named in or otherwise included within the “Perils Insured Against” clause. Nuclear hazards Radioactive (nuclear) pollution is a special form of physical pollution related to all major life-supporting systems – air, water and soil. But recovery is possible.3) Exposure at higher doses (400-500 rads), the bone marrow is affected, blood cells are reduced, natural resistance and fighting capacity against germs is reduced, blood fails to clot, and the irradiated person soon dies of infection and bleeding.4) Higher irradiation doses (10,000 rads) kill the organisms by damaging the tissues of heart, brain, etc.5) Workers handling radioactive wastes get slow but continuous irradiation and in course of time develop cancer of different types.6) Through food chain also, radioactivity effects are experienced by man.But the most significant effect of radioactivity is that it causes long range effects, affecting the future of man and hence the future of our civilization.Control of nuclear hazardsOn one hand, the peaceful uses of radioactive materials are so wide and effective that modern civilization cannot go without them; on the other hand, there is no cure for radiation damage. Various atmospheric conditions and climatic conditions such as wind, temperature and rainfall also determine their effects.All organisms are affected from radiation pollution, and the effects are extremely dangerous. ADVERTISEMENTS: The principal sources that are of environmental concern are the nuclear weapons and nuclear power reactors in the event of mishaps. Even it could be carried to future generations.2) Exposure at low doses of radiations (100-250 rads), men do not die but begin to suffer from fatigue, nausea, vomiting and loss of hair. No scientific organization of national or international standing disputes this. Still we are living with a hope that nothing will happen. Before we consider these hazards in detail we with examine the effects of the nuclear radiations on the life system. Nuclear safety is defined by the International Atomic Energy Agency (IAEA) as "The achievement of proper operating conditions, prevention of accidents or mitigation of accident consequences, resulting in protection of workers, the public and the environment from undue radiation hazards".
