摘要：
The paper deals with study of seasonal variation of outdoor and indoor radon in Somwarpet taluk, Coorg district using pin-hole dosimeter cups and LR-115(type II) films. The LR-115 films, placed in dosimeter cups with pin-holes, were exposed to radon in different seasons of the year. The annual inhalation dose due to outdoor and indoor radon ranges from 0.036 to 0.068 mSv year−1 and 0.53 to 0.75 mSv year−1 respectively. The radon levels are low, due to blocking of radon atoms in porespaces of porous soil, due to rainfall in all seasons.
