Distribution of 226Ra and 222Rn in bore well and lake water of Mysore Taluk, Karnataka State, India

摘要

The dose due to Ra-226 and Rn-222 concentration to the population of Mysore taluk through drinking water pathway was assessed using radon emanometry method. Radium-226 activity concentration varies from BDL to 73 mBql−1 with a median of 17.9 mBql−1 and Radon-222 concentration varies from 0.5 to 643.9 Bql−1 with a median of 23.8 Bql−1. Committed effective dose due to radium and radon concentration through drinking water path was found to vary from 15.6 to be 57.1 μSvy−1 with a geometric mean of 31.3 μSvy−1.
