摘　　要：为满足工程设计中450 kV的X射线探伤装置探伤室的屏蔽计算需求,引入ICRP Report 33、《辐射防护手册(第一分册):辐射源与屏蔽》中管电压在400~500 kV的X射线辐射屏蔽计算相关图表、参数,对现有《工业X射线探伤室辐射屏蔽规范》(GBZ/T 250-2014)进行补充和完善,对其中部分错误数据予以更正。修正后的规范可以适用于500 kV以下X射线探伤装置探伤室辐射屏蔽计算。To meet the radiation shielding calculation requirement for the room of 450 kV X-ray crack detection equipment in engineering design,the relevant chart and parameter are introduced from ICRP Report 33 and"Radiation Protection Handbook(Volume 1):Radiation Source and Shielding"for radiation shielding calculation of X-ray tube voltage from 400 to 500 kV which can supplement and improve the current specification of Inspection Room Radiation Shielding Specifications for Room of Industrial X-ray Radiography(GBZ/T 250-2014).According to this study,some errors in this specification of GBZ/T 250-2014 are found and corrected.The revised specification can be applied to the radiation shielding calculation for the room of X-ray crack detection equipment below 500 kV indeed.
