为了验证某铸造企业新建的通过式无损检测自动线辐射屏蔽措施的防护效果,分析和评价其工作场所及周围环境辐射状况,对其工作场所射线辐射剂量及其作业人员年接触剂量水平的现场检测和计算。结果显示,通过式无损检测自动线无损检测工作场所的射线辐射剂量在0.08~0.60μGy/h之间,作业人员年个人剂量当量-HP(10),即年有效剂量均小于0.01mSv,达到国家放射卫生防护标准的要求。提示,通过式无损检测自动线的辐射屏蔽防护措施效果良好,在正常运行时,能够保障检测工作人员和公众的身体健康与安全。
In order to verify the protective effect of a new type of non-destructive testing automatic line radiation shielding by a foundry enterprise, analyze and evaluate the radiation situation in the workplace and the surrounding environment, conduct on-site testing on the radiation dose in the workplace and annual exposure dose of workers Calculate. The results show that the radiation dose of the non-destructive testing automatic nondestructive testing workplace is between 0.08 ~ 0.60μGy / h, and the annual personal dose equivalent (-PH) of workers is less than 0.01mSv, reaching the national level Health protection standards requirements. Prompt, through the non-destructive testing automatic line of radiation shielding protective effect is good, in normal operation, to protect the detection of staff and the general public’s health and safety.
