Embodiment Construction
[0014] see Figure 1 ~ Figure 3 , The solid-state detector of the present invention includes a scintillation crystal 5 formed of cesium iodide or cadmium tungstate and a photodiode 4 coupled thereto. When the size of the scintillation crystal 5 and the photodiode 4 do not match, a light guide 9 can be arranged between the two. Said scintillation crystal 5, photodiode 4 or light guide 9 are contained in a housing made of nickel-plated brass material. The housing is composed of a shell 1 and a lower cover 7 . The inner wall of the housing 1 is a plane, and the lower cover 7 is stamped with a convex portion 10, which fits into the bottom port of the housing 1, and a covering edge 11 is left around the convex portion 10 to close the bottom plane of the housing 1, and paint on the sealing part. There is a coating layer that can avoid light and moisture. A rubber pad 6 and a lead sheet 8 are provided in the casing to fasten the scintillation crystal 5 including the light guide 9 ...
