目的了解和掌握淮安市放射防护现状,为预防和控制职业性放射病提出相应的防护对策。方法依据国家放射卫生标准开展主动性监测工作,主要包括医用X射线诊断设备防护性能监测和放射工作场所防护监测、放射工作人员职业性外照射个人剂量监测、放射工作人员辐射效应监测。结果医用X射线诊断设备防护性能监测合格率为95.5%,放射工作场所防护监测合格率为98.9%;个人剂量监测结果显示所有受监测放射工作人员的年有效剂量均低于2m Sv,人均年有效剂量为0.751 m Sv,介入放射学人均年有效剂量最高(0.833 m Sv);放射工作人员辐射效应监测结果显示,辐射相关指标异常率核医学岗位最高(28.6%)。结论各哨点单位放射防护基本良好,但需要进一步完善,应切实贯彻执行各项放射防护管理制度并加强日常监督检查,重点关注介入放射学、核医学岗位的辐射防护工作。
Objective To understand and grasp the current situation of radiation protection in Huai’an and propose corresponding countermeasures for prevention and control of occupational radiation sickness. Methods According to the national standards of radiation health, we carried out proactive monitoring, including the monitoring of protective performance of medical X-ray diagnostic equipment and the monitoring of radiation workplace protection, the personal radiation dose monitoring of radiation workers and the radiation effects monitoring of radiation workers. Results The qualified rate of protective performance of medical X-ray diagnostic equipment was 95.5%, and the rate of radioactive workplace monitoring was 98.9%. The individual dose monitoring results showed that the annual effective doses of all radiation workers under monitoring were lower than 2m Sv, and the per capita annual effective The radiation dose was 0.751 mSv, and the annual per capita effective dose of interventional radiology was the highest (0.833 mSv). The radiological monitoring results of radiation workers showed that the radiation-related abnormality rate was highest (28.6%) in nuclear medicine. Conclusions The sentinel units are basically good in radiological protection, but they need to be further perfected. The radiation protection management system should be implemented and the routine supervision and inspection strengthened. The radiation protection work involved in radiology and nuclear medicine should be given special attention.
