Determination of Radon Concentration in Groundwater of Areekode Region, Kerala, India — A Case Study

The primary factors in the radiation exposure received by the human population from soil and water are natural radioactivity, uranium isotopes, and thorium isotopes. High levels of nuclear radiation exposure are now one of the leading causes of cancer. Radon and its offspring in the biosphere have long been the topic of research. Various experts from all over the world have undertaken several investigations on the quantity of radon in surface and groundwater supplies. An attempt was made to measure the levels of radon in groundwater in and around Areekode using a smart radon monitor (SRM) developed by the Baba Atomic Research Centre (BARC) in Mumbai. Groundwater/Bore well water in this region had 222Rn in concentrations ranging from 0.37±0.03Bq/L to 3.53±0.10Bq/L. The environmental protection agency’s allowable limit of 11.1 kBq/m3 was met by all of the samples.
