2016-2017年介入放射学工作人员职业性外照射个人剂量水平调查分析
|
摘要
目的调查介入放射学工作人员的职业性外照射个人剂量水平和防护现状,为加强介入放射学工作人员的放射防护与监督管理提供科学依据。方法采用热释光剂量测量方法监测介入放射学工作人员职业性外照射个人剂量当量H_p(10),利用X、γ散漏射线巡测仪451P检测DSA设备透视防护区空气比释动能率。结果 2016年共监测介入放射工作职业性外照射757人,有效监测536人,有效监测率为70.81%,人均年剂量当量为1.29 mSv;2017年共监测1 123人,有效监测309人,有效监测率为27.52%,人均年剂量当量为1.47 mSv;2017年不同岗位放射工作人员人均年剂量当量的差异有统计学意义(χ~2=11.612,P<0.01);第二术者位总体空气比释动能率要高于第一术者位,且头部空气比释动能值均高于其他部位。结论 2016—2017年介入放射学工作人员的外照射个人剂量处于较低剂量照射水平但有效监测率偏低;放射防护工作仍需不断完善,重点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。
Objective To investigate the individual dose level and protection status of occupational external radiation of interventional radiology staff, and to provide scientific basis for strengthening the radiation protection and supervision management of interventional radiology staff.Methods The Thermo Luminescence dosimetry(TLD)of LiF(Mg,Cu,P)was used to monitor the personal dose equivalent H_p(10)of occupational external exposure of the interventional radiology staff, and the X, γ diffuse ray patrol instrument 451 P was used to detect the air kerma rate of the DSA equipment in the see-through protection zone.Results In 2016, a total of 757 occupational external exposures for interventional radiology were monitored, and 536 people were effectively monitored. The effective monitoring rate was 70.81%, and the per capita annual dose equivalent(mSv) was 1.29 mSv. In 2017, a total of 1,123 people were monitored and 309 people were effectively monitored. The effective monitoring rate was 27.52%, and the per capita annual dose equivalent(mSv) was 1.47 mSv; the difference of the per capita annual dose equivalent among radiationstaff was statistically significant in different positions in 2017(χ~2=11.612, P<0.01).The total air kerma rate in the second surgeon position was higher than the first surgeon position,and the head air kerma energy value was higher than other positions.Conclusion The personal dose of external radiation for interventional radiology staff in 2016—2017 is at a lower dose level, but the effective monitoring rate was low. The radiation protection work still needs to be continuously improved, and the emphasisshould be on strengthening radiation protection training for interventional radiology staff and their manage.
