X射线探伤(又称工业无损探伤)广泛应用于机械制造、石油及化工等工业,已成为检查金属或非金属物体内部缺陷的主要方法之一。根据作业场地与设备的不同,X线探伤作业可分固定式和移动式两种。前者是在探伤室内对被检物体进行透照检查,探伤室的防护墙有屏蔽射线作用;后者是用移动式或推带式X射线探伤装置在室外、生产车间或安装现场对被检物体进行透照检查,场地防护条件较复杂。本文仅对上述探伤作业场所放射防护中的有关问题进行讨论。
X-ray inspection (also known as industrial non-destructive testing) is widely used in machinery manufacturing, petroleum and chemical industries, has become the inspection of metallic or non-metallic objects one of the main methods of internal defects. According to the different job site and equipment, X-ray inspection work can be divided into two kinds of fixed and mobile. The former is in the detection of indoor inspection objects were transillumination inspection, testing room protective wall shielding ray effect; the latter is the use of mobile or push belt X-ray detection device in the outdoors, the production workshop or the installation of objects on the scene To carry out transillumination inspection, site protection conditions more complicated. This article only on the above-mentioned test site radiological protection issues related to the discussion.
