某工业^(192)Ir放射源探伤室辐射屏蔽设计探讨

Discussion on shield design of industrial^(192)Ir gamma detection room

以某公司γ射线检测探伤室为例,依据国家职业卫生标准《工业γ射线探伤放射防护标准》中相关要求,根据探伤室平面布局,以探伤室屏蔽墙、屋顶及防护门外30 cm处为辐射剂量关注点,通过相关经验公式及MCNP模拟计算各关注点辐射剂量率水平,分析了探伤室设计过程中辐射屏蔽薄弱区域及辐射安全措施,为工业探伤室的设计等提供一定的技术参考。

This paper is based on a companyγ-ray detection chamber.According to the national occupational health standard in Industrialγ-ray Detection Radiation Protection Standard,according to the layout of the testing chamber shielding wall,roof and protective door for the radiation dose focus,through the relevant experience formula and mcnp simulation of the concern radiation dose rate level,and analyzed the radiation shielding area of weak chamber design and radiation safety measures,provide certain technical reference for the design of industrial testing chamber.
