Gamma rays have strong penetrability, and radiographic testing is a method of testing using the penetrability and straightness of gamma rays. Although gamma rays cannot be directly detected by the naked eye like visible light, they can make photographic film sensitive and can also be received by special receivers. When gamma rays pass through (irradiate) a substance, the higher the density of the substance, the more the intensity of the radiation decreases, that is, the intensity at which the radiation can pass through the substance decreases. At this point, if photographic film is used for reception, the sensitivity of the film will be low; If instruments are used to receive, the signal obtained will be weak. Therefore, when using gamma rays to irradiate the parts to be inspected, if there are defects such as pores and slag inclusions inside, the density of the material transmitted through the path with defects is much smaller than that of the path without defects, and the intensity of the radiation is reduced less. That is, the transmitted intensity is greater. If a negative film is used to receive it, the sensitivity is greater, and the plane projection of the defect perpendicular to the direction of the radiation can be reflected from the negative film; If other receivers are used, instruments can also be used to reflect the plane projection of defects perpendicular to the direction of the radiation and the transmittance of the radiation. In general, gamma ray inspection is not easy to detect cracks, or in other words, gamma ray inspection is not sensitive to cracks. Therefore, gamma ray inspection is highly sensitive to volumetric defects such as porosity, slag inclusion, and incomplete penetration. Gamma ray flaw detection is suitable for detecting volumetric defects, but not for detecting area defects. The working principle of the X-ray detector and the X-ray detector
