Abstract

Abstract:

Seasonal variation of indoor radon, thoron and their progeny concentrations have been measured in different types of buildings at different locations of Belur and Channarayapatna taluks using time integrated passive radon dosimeters containing LR-115 Type II solid state nuclear track detector. The average radon and thoron activity concentrations, their progeny levels, life time fatality risk and annual effective dose due to radon and thoron were estimated in summer, rainy, autumn and winter seasons. A detail analysis of radon and thoron distribution in twenty different houses with seasonal variation is presented in this paper. In general, the levels of radon and thoron concentration were observed to be highest in winter and lowest in summer.
