某核燃料元件生产线放射性职业病危害因素水平调查

A Survey about the Level of Radioactive Occupational Hazards Existing in a Product Line of Nucleus Fuel-Element

目的为了解某核燃料元件生产线放射性职业病危害因素水平。方法通过现场放射性职业病危害因素调查、监测和个人剂量估算,对放射性工作人员的辐射危害程度进行分析。结果该燃料元件厂主要岗位的放射性气溶胶铀浓度均低于该生产线的控制值;工作场所γ辐射剂量率除气化罐附近、燃料棒外观检查超过了相关标准,其余岗位的γ辐射剂量率均符合标准要求;放射性工作人员的个人剂量能够控制在本生产线制定的管理目标值以内;结论该核燃料元件生产线在各项辐射防护措施正常运行情况下,其放射性职业病危害因素对工作人员的辐射危害程度在可接受范围内。

Objective To learn the level of radioactive occupational hazards existing in a product line of nucleus fuel - element. Methods Radioactive occupational hazardswas in workplace were investigated and monitored, personal doses were computered, and how much damage caused by harazds to workers was analyzed. Results The concentrations of uranium in main stations were lower than the control value. Except for the place near gasification filling and the surface of fuel robs, the radiation dose rates met the criteria in other stations. Pesonal doses could be controled under the target value. Conclusion The radioactive damage caused by harazds to workers are acceptable when all protections are in normal tuning.
