新疆煤中天然放射性和铀伴生煤矿潜在职业照射

目的 分析新疆煤中天然放射性水平和铀伴生煤矿的潜在职业照射。方法 根据近年来新疆煤中天然放射性水平调查的论文报道中的数据，分析比较新疆煤中天然放射性水平。结果 通过分析发现，新疆煤中²³⁸U活度浓度与世界、美国和俄罗斯相近，²³²Th活度浓度低于世界、美国和俄罗斯，²³⁸U和²³²Th活度浓度均低于我国平均浓度，在正常自然本底变化范围内。结论 从放射卫生学角度考虑，合理开发利用新疆的煤炭资源不会对矿工和居民的健康带来额外影响。

The level of natural radionuclide concentration in Xinjiang coal and potential occupational exposure to uranium associated coal mine

Objective Analysis of the level of natural radioactivity in Xinjiang coal and potential occupational exposure to uranium associated coal mine.Methods Base on the reported data on the natural radioactivity in Xinjiang coal in recent years, the level of natural radioactivity in Xinjiang coal was analyzed and compared.Results Through analysis, it was found that the concentration of ²³⁸U in Xinjiang coal was similar to the levels of the world average, the United States and Russia, and the concentration of ²³²Th was lower than those of the world average, the United States and Russia. Furthermore, the concentrations of ²³⁸U and ²³²Th were lower than the average concentrations in China, and they are within the range of normal natural background.Conclusion From the view point of radiological hygiene, rational exploitation and utilization of coal resources in Xinjiang will not affect the health of miners and residents.
