摘要
目的通过调查和分析石家庄市核医学工作人员的职业性外照射个人剂量水平,了解核医学工作人员的受照现状,为加强核医学工作人员的放射防护提供科学依据。方法采用热释光剂量测量方法对核医学工作人员个人剂量当量Hp(10)进行监测并分析有关数据。结果热释光剂量计置于铅衣外侧与铅衣内侧时测得的结果存在统计学差异(t=2.36,<0.05),使用铅衣能够使核医学工作人员受到的外照射剂量减少18%。不同岗位核医学工作人员所受的外照射剂量水平存在统计学差异(F=4.01,P<0.05),其中检验师组人均年剂量最低(1.66±0.34)m Sv,护士组人均年剂量最高(2.71±2.30)m Sv;经铅衣屏蔽后,不同岗位核医学工作人员受到的外照射剂量水平无差异(F=1.07,P>0.05)。结论铅橡胶防护用品在使用正确的前提下可以对核医学工作人员起到一定程度的保护作用;核医学工作人员中护士和技师的放射防护更应该引起重视。
Objective To investigate and analyze the occupational external exposure personal dose in shijiazhuang nuclear medical personnel, to master the actuality of external exposure in nuclear medicine personnel and provide the basis on strength- ening the radiological protection of nuclear medical personnel. Methods Personal dose equivalent Hp （10） was monitored in nuclear medical personnel through the thermolumineseence dose measurement the relevant data was analyzed. Results There was statistical difference in external exposure dose between the groups that had put thermoluminescence dosimeter outside and inside of the lead clothes （ t = 2. 36, P 〈 0.05 ）, external exposure dose had been reduced 18% for those using lead clothes. There were statistical differences in external exposure dose levels on different posts of nuclear medicine personnel （ F = 4. 01, P 〈 0.05 ）. The dose per person in the cwi group was the lowest （ 1.66 ：t： 0.34）, and the dose per person in the nurse group was the highest （2.71 ± 2.30） ; when using lead clothing, there was no difference between the cwi group and the nurse group （ F = 1.07, P 〉 1.07 ）. Conclusion lead rubber can play a part in protecting nuclear medicine personnel; The radiological protection of nuclear medicine nurses and technicians should be taken seriously.
