廊坊市放射工作人员个人剂量检测结果分析

目的了解不同工种、不同工作单位的放射工作人员职业外照射剂量情况。方法利用廊坊市疾病预防控制中心2006--2008年对廊坊放射工作人员个人剂量监测结果进行分析。结果2006--2008年放射工作人员个人年剂量当量（mSv／a）分别为1．292、1．243、1．363；从事放射诊断、工业探伤、同位素、介入治疗放射工作人员人均年剂当量（mSv／a）检测结果分别为1．265、1．410、1．232和1．999，两两比较，介入治疗与其他组比较，差异有统计学意义（P〈0．05）；不同工作单位放射工作人员个人剂量检测结果以乡镇卫生院最高（1．523mSv／a），市级医院最低（1．202mSv／a）。结论介入治疗工种工作人员的防护应引起注意，乡镇卫生院放射工作人员的防护应加强。

Analysis of Results of Detecting Individual Dose among Radiation Workers

Objective]To understand the occupational radiation dose among radiation workers of different types of work and different work units. Methods] The monitoring results of individual dose among radiation workers in Langfang from 2006-2008 by Langfang CDC were analyzed.Results] Average dose equivalent (mSv/a) of radiation workers was 1.292, 1.243,1.363 annually from 2006-2008; that of workers engaged in diagnostic radiology, industrial testing, isotope and interventional treatment was 1.265,1.410, 1.232 and 1.999 respectively. Compared each 2 groups, and Interventional treatment group with other groups, the differences were significant (P＜0.05); the individual dose of workers in health clinics of townships was highest (1.523 mSv/a) and lowest in municipal hospitals(1.202 mSv/a).Conclusion]The protection of workers who engaged in interventional treatment should be attached importance, and that of workers in health clinics of townships should be enhanced.
