通过了解宝鸡市放射工作人员个人剂量监测现状和外照射受照水平,分析个人剂量有效监测情况。按照《职业性外照射个人监测规范》的要求,采用热释光剂量方法进行常规检测,采用资料法、对比法进行比较。结果显示,有效监测率为49.6%,年集体有效剂量为137.7(人.mSv),人均年有效剂量为0.7mSv/a,受照剂量最大的职业类别为核医学,其次为医用放射诊断学与工业同位素使用。提示,宝鸡市放射工作人员有效监测率偏低,应加强执法力度。
By understanding the status of personal dose monitoring and radiation exposure of radiation workers in Baoji City, we analyzed the effective monitoring of personal dose. Accordance with the “Occupational Exposure to Personal Monitoring Norms” requirements, the use of thermoluminescence dose method for routine testing, the use of data methods, comparison method for comparison. The results showed that the effective monitoring rate was 49.6%, the annual effective dose was 137.7 (mSv), the effective annual per capita dose was 0.7mSv / a, and the highest occupational exposure category was nuclear medicine, followed by medical diagnostic radiology Industrial isotope use. Prompted, radioactive workers in Baoji effective monitoring rate is low, should strengthen law enforcement efforts.
