2022年眉山市非医疗放射工作单位辐射防护调查分析

Investigation and analysis of radiation protection of non-medical radiation units in Meishan 2022

目的为掌握眉山市非医疗放射工作单位底数及分类和分布情况,了解其放射性职业病危害防治管理现状、放射工作人员职业健康管理等情况,监测其工作场所放射性危害因素辐射水平,保护非医疗机构放射工作人员职业健康。方法2022年采用普查的方式对眉山市辖区范围内全部非医疗放射工作单位基本情况进行调查,并根据调查结果,选择不同类型企业开展工作场所X、γ辐射剂量率辐射水平进行检测;采用WPS Excel软件处理数据,采用描述性分析方法进行数据分析。结果2022年眉山市调查非医疗放射工作单位26家,涉及6类职业照射类别、源项323枚(台)、放射工作人员154人,除行包检测仪外的用人单位个人剂量监测率达100.00%、放射工作人员的放射防护培训率为93.50%、放射性职业健康检查率为94.80%、个人剂量报警仪配置率为66.67%、个人防护用品配置率为58.33%,行包检测工作单位从业人员均未按照放射工作人员管理。2022年对14家非医疗放射工作单位工作场所辐射水平进行检测,其检测结果均符合相应标准。结论眉山市非医疗放射工作单位涉及类别、源项、人员较多,放射性工作人员辐射防护管理不足;眉山市应当继续开展相应的调查和现场辐射水平检测,卫生监督机构应加大对非医疗放射工作单位的监督执法力度,提高非医疗放射性职业健康危害因素的管理水平,保护相关放射工作人员的职业健康权益。

Objective In order to master the base number,classification and distribution of nonmedical radiation work units in Meishan,to understand the status of prevention and management and occupational health management of radioactive personnel,to monitor the radiation level of radioactive hazard factors in the workplace,so as to protect the occupational health of staff of nonmedical radiation units.Methods The basic information of all non-medical radiation work units within the jurisdiction of Meishan was investigated,and according to the results of investigation,different types of enterprises were selected to detect radiation levels of X andγ;The WPS Excel software was used to process data and the descriptive analysis method was used for data analysis.Results In 2022,about 26 non-medical radiation work units were investigated in Meishan,involving 6 types of occupational irradiation,324 source items(stations),and 154 radiation workers.Except the staffs of package detector unit,the personal dose monitoring rate reached100.00%,the radiation protection training rate for radiological workers was 93.59%,and the rate of radioactive occupational health examination was 94.80%,and the configuration rate of the device for dose alarm and the protective equipment of the detector for personal was 66.67%and 58.33%.Employees of package detector unit were not managed in accordance with radiation staff.In 2022,Meishan city tested the radiation levels in the workplaces of 14 non-medical institutions,and the test results all met the corresponding standards.Conclusions The non-medical radiation work units in Meishan City involve many categories,sources and personnel,the radiation protection management of radioactive workers is insufficient;Meishan City shall continue to effectively carry out the corresponding investigation and on-site radiation level detection,and the health supervision institutions shall strengthen the supervision of non-medical radiation institutions,the occupational health management level of non-medical radiation should be improved,and the occupational health rights and interests of the relevant medical radiation workers should be protect.
