Description 467-471
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 100Bq.m-3), and vary from 7 to 452 Bq.m-3with an average
value of 154 ± 111 Bq.m-3 (GM 112Bq.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.
