辐射

Based on the analysis results and the principle that the concentration of the contaminants in a mine varies in a constant ratio and the degree of their hazard varies in an arithmetic progression,the evaluating indicators were determined for the air quality in a uranium mine,and an evaluation model was proposed for the evaluation of the air quality in a uranium mine based on integrated scale index on ...

该模型克服了传统评价方法主要从辐射危害的角度进行评价的局限，能综合评价铀矿山井下空气的质量。采用该模型对某铀矿井4个用风点的空气质量进行了评价，获得了4个用风点空气质量综合评价等级和应采取的相应的对策。评价结果能为铀矿井通风系统的设计和空气质量的安全评价提供参考。
