【摘要】 目的:对某铀矿山井下作业职业病危害因素及存在的职业卫生(辐射防护)问题提出有效的防护对策和建议。方法:依据国家有关辐射防护标准,采用理论计算法、类比调查法和经验法,对铀矿山井下作业场所中可能存在的辐射源项进行识别,并根据设计参数对辐射源项进行定量分析与评价。结果:铀矿山井下存在氡及其子体、γ外照射、放射性粉尘和放射性气溶胶以及β外照射。在正常生产条件下,作业人员所受的辐射年有效剂量预计为11.89mSv,可以控制在目标管理值范围内。结论:本项目属于严重职业病危害项目。从职业病防治角度分析,项目建设可行。更多还原

【Abstract】 Objective To put forward the effective countermeasure,proposal for the future problems of radiological protection in the construction projective of an uranium mine through the pre-evaluation of occupational hazards.Methods Based on the related national standards for radiation protection,the assessment were carried out using combination of analogy,therology calculation and experience.Radiational items in the workplace of the uranium mine were identified,and quantitative analysis were used to assess the radiological harzads according to the designed parameters.Results The were radon and its daughters,γ and β radiation,radiological dust and aerosol in the project.In the ordinary workng conditon,the predicted effective doses that the woker received was 11.89 mSv per year,this was under the admistrative object.Conclusion The project belongs to be the serious occupational hazard project,but according to occupational aspect,the construction project is feasible.更多还原
