Zusammenfassung: | PROBLEM TO BE SOLVED: To obtain a building for radiation facility, which enables an effective use of the building space, and can cut down construction expenses. SOLUTION: A pair of crane garters 15 are formed inner wall surfaces of walls in upper part sides of oppositely faced sidewalls 13, which are dented, respectively, and an overhead crane 7 is constructed on the pair of the crane garters 15. When the wall thickness of the lower part of the sidewall 13 is called 'a', the wall thickness of the upper part of the sidewall 13 is called 'b', the width of the crane garter is called 'c', and the angle which is made by the line segment which connects the center O of the radiation source of the accelerator 5 to an inner edge P of the crane garter 15, and the horizontal line is called θ, the wall thickness 'b' of the upper part of the sidewall 13 is formed so that b>=a.cosθ, and b |
