目的分析石家庄市某三甲医院介入工作人员2015年度外照射个人剂量监测水平,为进一步做好放射防护工作提供参考依据。方法使用Li F(Mg,Cu,P)热释光剂量计(TLD)定期监测,并使用SPSS软件进行处理分析,依据国家有关法律法规和技术标准进行评价。结果 2015年间某院介入放射工作人员的年有效剂量为0.26~5.26 m Sv/a,其中内科介入放射工作人员的年均有效剂量最高,为0.83 m Sv/a;某院94.3%~98.8%介入工作人员的年有效剂量<1 m Sv/a,剂量水平低于2015年石家庄三甲医院介入放射工作人员人年均剂量1.50 m Sv/a。结论某院剂量监测管理工作到位,但应加强重点科室放射操作管理及员工放射防护的教育与培训。
Objective To analyze the personal radiation dose monitoring level of interventional workers in a top three hospital in Shijiazhuang in 2015, which provides a reference for further radiological protection. Methods The LiF (Mg, Cu, P) thermoluminescence dosimeter (TLD) was used for routine monitoring and analysis using SPSS software. The method was evaluated according to relevant national laws, regulations and technical standards. Results The annual effective dose of interventional radiology staff in a hospital from 2015 to 2015 was 0.26-5.26 m Sv / a, of which the annual average effective dose of interventional radiological staff was the highest (0.83 m Sv / a); 94.3% -98.8% The annual effective dose of the staff is less than 1 m Sv / a, and the dose level is lower than the annual average dose of 1.50 m Sv / a for the interventional radiographers in the top three hospitals in Shijiazhuang in 2015. Conclusion The dose monitoring and management of a hospital is in place, but the education and training of radiation operation management and staff radiological protection in key departments should be strengthened.
