When in atmosphere harmful changes happen due to different types of radiations and radioactive materials then it is called radiation pollution. It is the physical pollution of air, water and soil with radioactive materials. It is natural as well as man made. The effect of radioactive pollutants depend on (i) strength of radiation, (ii) rate of diffusion and deposition of the pollutants, (iii) the length of time for which the tissue is exposed to radiation, and (iv) half life of pollutants. Environmental factors also influence their effects.
Effect of radiation pollution:–
(1) Due to radiation pollution, body becomes weak and life becomes short.
(2) Radiation pollution is harmful for DNA, RNA, Protein, Spleen, etc.
(3) Radioactive radiations cause sterility, defect vision, tumour of lungs, loss of tissues, etc.
(4) Long time exposure in ultraviolet radiations causes skin related ****.
(5) For long time or time-to-time radiation of radioactive materials may cause blood ** or leukaemia.
(6) Cells vary in their sensitivity to injury by radiation.
(7) Chances of depletion of ozone layer in stretosphere by nuclear explosions.
