Hazards of nuclear wastes are:

(i) Nuclear waste contains radioactive substances which emit harmful nuclear radiations.

(ii) There is a high risk of environmental contamination.

(iii) It is highly toxic.

Effect of nuclear waste on plant and animal life is:

The radiations emitted from the nuclear waste penetrate deep inside the human or animal body where they can damage biological cells thereby initiate cancer or causes genetic disease.

Increased mortality of plants, soil invertebrates and mammals and reproductive losses in plants and animals have also been observed.
