Concentration of radon and physicochemical parameters in ground water around Kolar Gold Fields, Karnataka State, India

Abstract

Concentration of radon and physicochemical parameters present in ground water collected from 65 bore wells of 30 different locations around Kolar Gold Fields, Kolar District, India are estimated by emanometry technique and chemical analysis. Activity of radium present in rock samples of the study area using HPGe detector are presented and discussed in the manuscript. The average radon concentration in the collected water samples are ranged from 3.3 ± 0.8 to 122.9 ± 2.1 Bq l−1 with an average value of 46.9 ± 1.7 Bq l−1. Average value of activity concentration of radium is found to be 29.1 Bq kg−1.
