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.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
