Abstract
The present study reports the terrestrial gamma radiation exposures in dwellings in Makum Coalfield, India, using a Micro-R Gamma Survey Metre. The geometric means (GMs) of indoor and outdoor gamma dose rates were found to be 150.3 ± 7.4 nGy h−1 and 129.2 ± 6.6 nGy h−1, respectively, which are considerably higher than the global population-weighted average of 84 nGy h−1 and 59 nGy h−1, respectively. The estimated GMs of annual effective dose equivalents and excess lifetime cancer risks were also found to be substantially higher than the global recommended values of 0.48 mSv y−1 and 1.45 × 10–3, respectively.
