目的分析放射工作人员剂量异常原因,保证监测数据的真实可靠。方法发放调查表格,结合现场调查和电话咨询核实个人剂量异常原因,并对其进行分析及处理。结果非正常照射人次占剂量异常人次的92.3%,其主要原因是放射工作人员的故意照射和把剂量计遗留机房内,正常照射的主要原因是放射工作人员在进行床边射线诊治操作时不注意穿戴足够的个人防护装备。结论放射机构应采取措施,改善工作场所和人员防护条件,提高管理水平,落实管理责任制,加强防护知识培训和宣传贯彻个人剂量监测的有关规定;放射监测服务机构应提高监测质量,确保监测数据的准确性。
Objective To analyze the causes of abnormal dose of radiation workers to ensure the real and reliable monitoring data. Methods Disseminating the questionnaire, combining field investigation and telephone consultation to verify the cause of abnormal dose and analyzing and dealing with it. Results Abnormal radiation exposure accounted for 92.3% of the total abnormality. The main reason was that the radiation workers deliberately irradiated and the dosimeter was left in the engine room. The main reason for the normal radiation was that radiographers did not pay attention to the operation of bedside ray diagnosis and treatment Wear adequate personal protective equipment. Conclusion Radiological agencies should take measures to improve the workplace and personnel protection conditions, improve the management level, implement the management responsibility system, strengthen the protection of knowledge training and publicity to implement the relevant provisions of individual dose monitoring; radiation monitoring services should improve the quality of monitoring to ensure that the monitoring data Accuracy
