了解烟台市放射工作人员职业外照射个人剂量水平。采用热释光个人剂量测定方法对烟台市接触职业照射的医疗单位及工厂企业工作人员等进行监测。结果显示,烟台市放射工作人员有效监测率为95.7%,2012年的人均年剂量当量为0.52mSv;不同单位中,以医院工作人员职业外照射人均年剂量当量最高(0.61mSv),其次为工厂企业(0.44mSv),不同单位的工作人员人均年剂量当量比较,差异有统计学意义(P<0.05)。提示,烟台市放射工作人员职业外照射个人剂量处于较低水平,放射防护工作效果良好。
Understand Yantai City radiation staff occupational exposure to individual dose levels. Using thermoluminescence personal dosimetric method to monitor exposure to occupational exposure in Yantai medical units and factories and enterprises staff. The results showed that the effective monitoring rate of radiation workers in Yantai City was 95.7%, and the average annual equivalent dose per capita was 0.52mSv in 2012. The highest equivalent per capita annual equivalent dose of hospital staff (0.61mSv) was in different units, followed by the factory Enterprises (0.44mSv), different units of staff per capita annual dose equivalent comparison, the difference was statistically significant (P <0.05). Tip, Yantai radiation staff occupational exposure to individual doses at a low level, radiological protection work well.
