उत्तर
Nuclear waste: Nuclear waste is the material that nuclear fuel becomes after it is used in a reactor.
Hazards of nuclear waste:
(i) Nuclear waste can cause environmental contamination which can affect the health of millions of people.
(ii) Nuclear waste is the source of radiations which can lead to the following disorders:
(a) Radiations can cause genetic disorders.
(b) These can cause leukemia.
(c) These can destroy the immunity and hence may lead to death.
(d) Long exposure to radiation can cause cancer, blindness etc.
