| 摘 要： | 介绍了2017年浙江省宁波地区一起工业探伤作业(^75Se放射源)射线误照射事件和该事件处理情况。根据调查及保守剂量估算结果,本次事件中现场非探伤作业人员所受误照射剂量估计值约为29.54μSv,该估算剂量小于1mSv的公众年有效剂量当量限值,也小于0.25mSv每年的管理限值,管理部门根据调查和计算结果将本次误照射定性为辐射事件并通过该事件经验反馈提出监管建议。

| Abstract: | A radiation event in an operation of industrial flaw detection in Ningbo, Zhejiang Province in 2017, is presented, along with treatment of it. Based on the survey and a conservative dose estimation,exposure dose of non-inspective workers on site was approximately 29.54 μSv,less than the annual management limit of 0.25 mSv, and also the public annual dose limit of 1 mSv. The management department accordingly identified the mis-irradiation of this time as a radiation event and provided regulatory advice via feedback. |
