Abstract

This present study investigates the levels of dose rates and the potential risks of exposure to terrestrial gamma radiations in both indoors and outdoors in houses in the vicinity of the Dilli-Jeypore coalfield of Assam, India. The measurements were carried out using a highly sensitive portable Micro-R Survey Meter (UR 705). Indoor gamma dose rates have been estimated to be in the range of 49.7 ± 5.1-154.9 ± 5.1 nGy h^-1, while outdoor rates varied between 49.7 ± 5.1 and 93.5 ± 5.1 nGy h^-1, with an indoor to outdoor dose rate ratio of 1.21. The geometric mean of annual effective dose equivalent (AEDE) was calculated to be 0.49 ± 0.03 mSv y^-1, which is slightly higher than the global recommended level of 0.48 mSv y^-1. The excess lifetime cancer risk (ELCR) was estimated to range from 1.1 × 10^-3 to 2.9 × 10^-3, with a mean of 1.72 × 10^-3.

印度Dilli-Jeypore煤田附近的地面伽马辐射和辐射安全问题调查。

本研究调查了印度阿萨姆邦Dilli-Jeypore煤田附近室内和室外房屋的剂量率水平和暴露于地面伽马辐射的潜在风险。测量使用高灵敏度便携式微r测量仪（UR 705）进行。据估计，室内γ射线剂量率的范围为49.7±5.1-154.9±5.1 nGy h-1，室外剂量率的范围为49.7±5.1- 93.5±5.1 nGy h-1，室内外剂量率比为1.21。计算得出年有效剂量当量（AEDE）几何平均值为0.49±0.03 mSv -1，略高于全球推荐水平0.48 mSv -1。估计过量终身癌症风险（ELCR）范围为1.1 × 10-3 ~ 2.9 × 10-3，平均值为1.72 × 10-3。

期刊介绍： Environmental Geochemistry and Health publishes original research papers and review papers across the broad field of environmental geochemistry. Environmental geochemistry and health establishes and explains links between the natural or disturbed chemical composition of the earth’s surface and the health of plants, animals and people. Beneficial elements regulate or promote enzymatic and hormonal activity whereas other elements may be toxic. Bedrock geochemistry controls the composition of soil and hence that of water and vegetation. Environmental issues, such as pollution, arising from the extraction and use of mineral resources, are discussed. The effects of contaminants introduced into the earth’s geochemical systems are examined. Geochemical surveys of soil, water and plants show how major and trace elements are distributed geographically. Associated epidemiological studies reveal the possibility of causal links between the natural or disturbed geochemical environment and disease. Experimental research illuminates the nature or consequences of natural or disturbed geochemical processes. The journal particularly welcomes novel research linking environmental geochemistry and health issues on such topics as: heavy metals (including mercury), persistent organic pollutants (POPs), and mixed chemicals emitted through human activities, such as uncontrolled recycling of electronic-waste; waste recycling; surface-atmospheric interaction processes (natural and anthropogenic emissions, vertical transport, deposition, and physical-chemical interaction) of gases and aerosols; phytoremediation/restoration of contaminated sites; food contamination and safety; environmental effects of medicines; effects and toxicity of mixed pollutants; speciation of heavy metals/metalloids; effects of mining; disturbed geochemistry from human behavior, natural or man-made hazards; particle and nanoparticle toxicology; risk and the vulnerability of populations, etc.
