【摘要】：目的探讨介入放射学工作人员受照剂量的调查水平,为其个人剂量监测中可疑数据的调查提供科学方法。方法收集2013年度13家医院介入放射学工作人员4个周期1 219对内、外热释光个人剂量计(TLD)的受照剂量监测资料,经统计分析甄别其TLD佩带情况。选取正确佩带TLD人员的受照剂量数据计算、确定其调查水平。对可疑数据,根据TLD佩带情况,结合内、外TLD的受照剂量确定调查内容。结果内、外TLD的受照剂量范围分别为最低探测水平(MDL)~17.91和MDL~25.57 m Sv。1 219对TLD中,正确佩带307对(占25.18%),对调佩带81对(占6.64%),混合佩带287对(占23.54%),不佩带内TLD者4对(占0.33%),540对无法判定佩带情况(占44.30%)。内TLD剂量的调查水平为2.27 m Sv,外TLD调查水平最小值为0.04 m Sv,最大值为46.23m Sv。根据介入放射学工作人员受照剂量的可疑数据确定相应的调查内容。结论应加强对介入放射学工作人员及其管理人员的辐射防护培训,定期修订其受照剂量的调查水平,当其受照剂量低于或高于调查水平时,应进行相应调查。
[Abstract]:Objective to explore the level of radiation dose survey among interventional radiology workers, and to provide a scientific method for the investigation of suspicious data in personal dose monitoring. Methods 1,219 pairs of interventional radiology workers in 13 hospitals in 2013 were collected. The radiation dose monitoring data of the external thermoluminescence personal dosimeter (TLDD) were analyzed and identified by statistical analysis. The radiation dose data of the correct wearing TLD personnel were selected to calculate the investigation level. For the suspicious data, according to the TLD wearing situation, In combination with the internal and external TLD, the contents of the investigation were determined. The results showed that the radiation dose range of the external TLD was in the lowest detection level (MDL) 17.91 and the MDL~25.57 m Sv.1 219 pairs of TLD, respectively. 307 pairs of correct wear (25.18m), 81 pairs (6.64%), 287 pairs of mixed wear (23.54%), 4 pairs of non-wearing TLD (0.33%) can not determine the wearing situation (44.30%). The investigation level of TLD dose is 2.27 m Sv, and the level of TLD investigation is the highest outside. The small value was 0.04 m Svand the maximum value was 46.23 m Sv.According to the suspicious data of exposure dose to interventional radiology workers, the contents of investigation were determined. Conclusion the radiation protection training of interventional radiology workers and their management personnel should be strengthened. The investigation level of radiation dose should be revised periodically, and the corresponding investigation should be carried out when the radiation dose is below or above the investigation level.
