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。
The purpose is to understand the level of radioactive occupational hazards in a nuclear fuel element production line. Methods According to the investigation, monitoring and personal dose of occupational hazards in the field, the degree of radiation hazards of radioactive workers was analyzed. Results The concentrations of radioactive aerosol uranium in the main positions of the fuel plant were lower than those of the production line. The γ radiation dose rate in the workplace was lower than that of the gasification tank and the appearance of the fuel rod exceeded the relevant standards. The γ radiation dose rate All meet the standard requirements; the personal dose of radioactive workers can be controlled within the management target set by this production line; Conclusion The radiation hazard of hazardous occupational hazards to staff members under the normal operation of radiation protection measures of this nuclear fuel component production line The extent is acceptable.
