# Write a note on Nuclear Hazards.

ANS:


* A nuclear blast can cause death of millions of people in a few seconds.

* It can damage huge structures like buildings.

* Heat produced during such blast can spread into large area destroying life.

* There are mainly two types of dangers from nuclear radiation : (1) Pathological danger (2) Genetic danger.

* Pathological effects cause diseases like cancer which may prove fatal.

* Genetic effects cause damage to the children of next generation in the form of various physical disabilities.

* Leakage of radiation from nuclear reactors adversely affect all spheres of the environment.

* The accidental leakage from a nuclear reactor in Chernobyl (Ukraine) in 1986 was so serious that about 50 tons of radioactive material had spread over a large area that thousands had died and about 2 lakh people had to be shifted to safer place. The radiation in this explosion was 200 times the radiation spread by the atomic bomb in Hiroshima and Nagasaki.

* The disposal of nuclear wastes, rods of nuclear fuel is a great problem as it spreads radiation continuously. Such material is at present buried very deep in the earth where it is unlikely to come in contact of underground water.
