Background radiation refers to the radiation emitted from natural sources similar as rocks or mountains. A recent study conducted by scientists at the Bhabha Atomic Research Centre( BARC) set up that certain areas in Kerala are passing nearly three times more background radiation than preliminarily assumed. The study is significant, as it sheds light on the natural radiation situations in India, which has important implications for the country’s nuclear energy plans.

Monazite sands and high situations of thorium :-

The advanced radiation situations in Kollam, a quarter in Kerala, are attributed to the presence of monazite sands that are high in thorium, a natural radioactive element. Thorium is a common radioactive element that's set up in small quantities in soil, rocks, and water. Monazite sands are one of the most important sources of thorium, and India has been using these sands as a source of nuclear energy for numerous times. Southern India, which is home to granite and basaltic stormy rocks, has advanced situations of radiation from uranium deposits.

Study findings :-

The study conducted by BARC scientists measured radiation levels from nearly 100,000 locales across India. The study set up that the average natural background situations of gamma radiation in India were 94 nGy/ hr. still, in Kollam district, the levels were set up to be,562 nGy/ hr, which is about three times further than the assumed levels. The 1986 survey conducted preliminarily had mapped only 214 locales.

No elevated health threat :-

Although the advanced radiation situations in Kollam quarter might feel concerning, the study’s authors note that there's no elevated health threat associated with these advanced radiation situations. The human body is oriented to high doses of radiation, and there's no substantiation to suggest that the high level of radiatsion in Kollam quarter are causing any adverse health goods.

IAEA safety norms:-

 The International Atomic Energy Agency( IAEA) specifies maximum radiation exposure levels, which have also been adopted by India’s atomic energy establishment. The IAEA recommends that public exposure to radiation shouldn't exceed 1 milli- Sievert every time, and those who work in nuclearplants or are exposed to radiation by virtue of their occupation shouldn't be exposed to over 30 milli- Sievert every time.
