Radon and thoron are significant contributors for radiological risk in indoors and are originating from decay chain of uranium and thorium, which are prevalent in the environment. These concentrations in indoors depends on the presence of uranium and thorium concentration, and lifestyle of the habitants. The village “Peddamula” is located in the neighbourhood area of proposed mining for exploration of uranium. The estimated concentration of radon and thoron is found in the range 14-448 Bq.m-3 with an average value of 120 ± 82 Bq.m-3 (GM 100 Bq.m-3), and vary from 7 to 452 Bq.m-3 with an average value of 154 ± 111 Bq.m-3 (GM 112 Bq.m-3), respectively. Computed the contribution to the effective dose per annum from, radon 3.02 mSv.y-1 and thoron is 4.32mSv.y-1. In this paper the seasonal variation and distribution of 222Rn and 220Rn levels in the dwellings of the study area will be discussed.

Radon and thoron are significant contributors for radiological risk in indoors and are originating from decay chain of uranium and thorium, which are prevalent in the environment. These concentrations in indoors depends on the presence of uranium and thorium concentration, and lifestyle of the habitants. The village “Peddamula” is located in the neighbourhood area of proposed mining for exploration of uranium. The estimated concentration of radon and thoron is found in the range 14-448 Bq.m-3 with an average value of 120 ± 82 Bq.m-3 (GM 100 Bq.m-3), and vary from 7 to 452 Bq.m-3 with an average value of 154 ± 111 Bq.m-3 (GM 112 Bq.m-3), respectively. Computed the contribution to the effective dose per annum from, radon 3.02 mSv.y-1 and thoron is 4.32mSv.y-1. In this paper the seasonal variation and distribution of 222Rn and 220Rn levels in the dwellings of the study area will be discussed.
