摘要
目的通过对2012年辽宁省放射工作人员外照射个人剂量监测结果的分析,了解和掌握监测区域内放射工作人员外照射个人剂量情况。方法热释光剂量法监测,分析不同工种间个人剂量监测值是否存在差异。结果监测值符合国家对放射工作人员的剂量限值要求;医学应用放射工作人员人均年有效剂量为(0.87±0.53)mSv·a-1高于工业应用工作人员(0.71±0.59)mSv·a-1,差异有统计学意义(P<0.01);所有职业中,核医学工作人员人均年有效剂量最高,为(1.010±0.387)mSv·a-1;工业应用中各职业人群个人剂量差异无统计学意义。结论应加强医学应用,特别是从事核医学工作的放射工作人员的监测防护工作,督促用人单位及时送检个人剂量计;进一步规范正确佩戴个人剂量计的方法。
Objective To master the monitoring area radiation dose in time through analysis of the 2012 radiation workers external exposure personal dose monitoring work analysis. Methods The difference of personal dose monitoring value between the different type of workers were analyzed through the thermoluminescence dose monitoring method and SPSS software. Results Liaoning province personal dose monitoring value conforms to the limit requirements,the monitoring value of the medical applicatioans is( 0. 87 ± 0. 53) mSv·a1,higher than the monitoring value of the industrial applications( 0. 71 ± 0. 59) mSv·a1( P 0. 01); the monitoring value of nuclear medicine workers( 1. 010 ±0. 387) mSv·a1is higher than that of other types. There are no obvious differences in industrial applications. Conclusion Strengthen the protection for the nuclear medicine workers,supervise and urge the employing units to have the personal dosage meter timely inspected and to help to wear the meter correctly.
