| 摘 要： | 通过对典型工业γ射线探伤室周围的现场监测，将探伤室周围的辐射吸收空气剂量率与GBZ132-2008中规定的剂量限值进行比较，进行了固定式γ射线探伤辐射防护措施的可行性分析。同时通过理论计算得到了使用放射源探伤时无防护措施可能造成的超大辐射剂量照射数据，有效印证了进行有效硬件防护以及与软件措施相结合，就能够在γ射线探伤实践中保护环境和从业人员的安全，同时也为管理部门提供技术支持。

| Abstract: | Based on the site monitoring around the industrial gamma ray flaw detection room,the radiation absorbed dose rate around testing room and the prescribed dose limits in GBZ 132-2008 were compared.The radiation protection measures feasibility of fixed type gamma ray flaw detection was analyzed.At the same time,through theoretical calculation the large radiation dose exposure data was obtained using radiation source inspection without protective measures.It was proved effectively that environment and personnel safety could be protected in gamma ray inspection by the combination of hardware protection and software protection,which provided technical support for management department. |
