Abstract
Samples of water from different thermal power plants in northern India have been collected and analysed for radium and radon concentration. For the me asurements, alpha -sensitive LR-115 type II plastic track detectors are use d. The radium and radon levels measured in some samples are high and thus u nsafe from health point of view. Based upon the available data. the radon e xhalation rates have been calculated. The radium concentration varies from 1.11 to 3.11 Bq l(-1) and the radon concentration varies from 10.64 to 29.7 8 pCi l(-1). The radon mass exhalation rates vary from 8.95 to 25.08 mBq kg (-1) hr(-1) and surface exhalation rates vary from 245.21 to 690.24 mBq m(- 2) hr(-1) in different water samples.
