为分析天津市河西区2010-2012年医疗机构不同放射工种以及不同级别医院的放射工作人员的外照射个人剂量水平。采用热释光个人剂量计对1 609名放射工作人员的外照射个人剂量水平进行监测。结果显示,人均年有效剂量为0.41mSv/a。介入治疗人员人均年有效剂量高于其他工种,其他医院(二级、社区、私人医院)人均年有效剂量大于三级医院。提示,天津市河西区医疗机构放射工作人员的年有效剂量均低于国家规定的剂量限值。介入治疗和私人诊所的放射人员为本区管理和监控放射人员个人剂量的重点。
In order to analyze the personal radiation dose level of radiation workers of different radiation workers and hospitals in different levels from 2010 to 2012 in Hexi District, Tianjin City. The personal exposure dose of 1 609 radiation workers was monitored using a thermoluminescent personal dosimeter. The results showed that the per capita effective dose of 0.41mSv / a. The annual per capita effective dose of interventional workers is higher than that of other types of work. The annual per capita effective dose of other hospitals (secondary, community and private hospitals) is more than that of tertiary hospitals. Tip, Hexi District, Tianjin Medical institutions, the effective doses of radiation workers are lower than the national dose limit. Radiographers at interventional and private clinics focus on managing and monitoring individual doses of radiographers in the district.
