[目的]了解重庆市工业射线探伤和密封放射源应用放射工作人员的个人剂量水平。[方法]采用热释光剂量测量法对重庆市2011—2012年共500名放射工作人员的职业外照射个人剂量进行监测。[结果]2011—2012年接受监测的272名工业探伤工作人员个人剂量范围为0.01～4.74mSv/a,人均个人剂量为0.145mSv/a;228名工业密封源应用人员个人剂量范围为0.0l～1.56mSv/a,人均个人剂量为0.075mSv/a。[结论]重庆市工业放射防护总体良好,工作人员个人剂量水平符合国家标准规定的年剂量限值,但工业探伤高于密封源应用工作人员的人均年有效剂量。
[Objective] To understand the personal dose level of radiation workers employed by industrial radiographic testing and sealed radioactive sources in Chongqing. [Method] The personal exposure dose of 500 radiation workers in Chongqing from 2011 to 2012 was monitored by thermoluminescence dosimetry. [Results] The personal dose range of 272 industrial testing workers monitored from 2011 to 2012 ranged from 0.01 to 4.74 mSv / a, and the average per capita dose was 0.145 mSv / a. The personal dosage of 228 industrial sealed source workers ranged from 0.0l ~ 1.56mSv / a, the average per capita dose of 0.075mSv / a. [Conclusion] The industrial radiological protection in Chongqing is generally good and the personal dose level of workers accords with the annual dose limit stipulated by the national standards. However, the industrial average per capita effective dose for industrial flaw detection is higher than that of sealed source workers.
