Context
The Bhabha Atomic Research Centre (BARC) has found that ‘background radiation’ levels are nearly three times more than what’s been assumed in the State of Kerala.
Findings of the report:
1 Gray is equivalent to 1 Sievert, though one unit refers to radiation emitted and the other to biological exposure. |
About the Background Radiation:
Radon is a gas that can concentrate indoors and be inhaled, along with its decay products. |
The International Atomic Energy Agency (IAEA) specifies maximum radiation exposure levels and this has also been adopted by India’s atomic energy establishment. |
Source of background radiations:
Natural Source: Natural sources, such as the earth, air, building materials, and food, provide the majority of background radiation. Cosmic rays from outer space also contain radiation.
Artificial Source: Human activity, on the other hand, has increased background radiation by building and employing artificial radiation sources.
Verifying, please be patient.
