NUCLEAR HAZARD:-
Radioactive (nuclear) pollution is a special form of physical pollution related to all major life-supporting systems – air, water and soil. It is always convenient to discuss radioactive pollution separately because its nature of contamination is different from other types of pollution. Its effects are also of special kinds.
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. The emission of energy from radioactive substances in the environment is often called as 'Radioactive Pollution'.
SOURCE OF NUCLEAR HAZARD
The sources of radioactivity are both natural and man-made. The natural sources include:
1) Cosmic rays from outer space. The quantity depends on altitude and latitude; it is more at higher latitudes and high altitudes.
2) Emissions from radioactive materials from the Earth's crust.

Hello Dude,
Let me answer this question...
The principal sources that are of environmental concern are the nuclear weapons and nuclear power reactors in the event of mishaps. Before we consider these hazards in detail we with examine the effects of the nuclear radiations on the life system.
A number of nuclear explosions have already been made during recent past in different pa of world. Irrespective of judgments about the ethics of this practice, these tests occurred, injecting substantial amounts of radioactivity into the environment. Nuclear explosions are very rapid and based on a rough estimate, in an explosion about 50 per cent of the energy goes to the blast, 33 per cent as heat and the rest 17 per cent or so to radioactivity.
The radioactive dust that falls to the earth after atomic explosion is called radioactive fallout. The estimated percept dose to world population from fallout of past nuclear explosions is 10 microsievert per year.
Hope it helps.
Thankyou!
