2016—2018年成都地区部分放射从业人员个人剂量监测异常结果分析

目的 对2016—2018年成都地区部分放射从业人员个人剂量监测异常结果进行分析，以采取相应措施避免同类异常情况。方法 采用热释光测量法监测个人剂量，采用SPSS19.0统计软件对监测结果进行分析。结果 2016—2018年异常剂量人次数基本持平，不同年份异常剂量人次差异无统计学意义（P > 0.05）；从事诊断放射学的人员个人剂量异常人次最多，占75.96%；个人剂量异常原因居首位的是“个人剂量计曾经被留置于放射工作场所内”，占32.61%。结论 应进一步加强剂量计规范佩戴管理。

Analysis on the abnormal results in individual dose monitoring of some radiation workers in Chengdu area from 2016 to 2018

Objective To analyze the abnormal results of individual dose monitoring of some radiation workers in Chengdu from 2016 to 2018, so as to take corresponding measures to avoid similar abnormal situations.Methods The individual dose was monitored by thermoluminescence method, and the monitoring results were analyzed by spss19.0 statistical software.Results From 2016 to 2018, the number of people with abnormal dose was basically the same, and there was no significant difference in the number of people with abnormal dose in different years (P > 0.05); the number of people engaged in diagnostic radiology with abnormal personal dose accounted for 75.96%; the first reason for the abnormal personal dose was that "the personal dosimeter had been left in the radiation workplace", accounting for 92.55%.Conclusion The main reason for the abnormal results is that the dosimeter is not worn properly, so the management should be further strengthened.
