Ionizing radiations: Radiation pollution - Environment & Biodiversity
Q. Radiation pollution is in the increase. Which radiations are considered pollutants?- Published on 31 Aug 15
a. Non - ionizing radiations
b. Ionizing radiations
c. Both Ionizing and Non - ionizing radiations
d. Background radiation
ANSWER: Ionizing radiations
We live in an environment of natural radiations there is a certain amount of radioactive radiations almost everywhere on the earth. These are only rarely harmful as the radiation level is generally quite low. This small level of radioactive radiation which is present everywhere is called the background radiation. The ionizing radiations cause damage to biological systems and are, therefore, pollutants. They ionize atoms and molecules.
