摘要

本研究利用微型伽马测量仪（Micro-R Gamma Survey Metre）报告了印度马库姆煤田住宅的地面伽马辐射暴露情况。室内和室外伽马辐射剂量率的几何平均数（GMs）分别为 150.3 ± 7.4 nGy h-1 和 129.2 ± 6.6 nGy h-1，大大高于全球人口加权平均值（分别为 84 nGy h-1 和 59 nGy h-1）。年有效剂量当量和超额终生癌症风险的估计全球机制值也分别远高于 0.48 mSv y-1 和 1.45 × 10-3 的全球建议值。

Assessment of terrestrial gamma radiations and radiological risks in Makum Coalfield, India

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.
