RADIATION MEASURING DEVICE ADAPTABLE TO SURFACE SHAPE TO BE MEASURED

摘要

PROBLEM TO BE SOLVED: To measure directly and efficiently surface contamination of a measuring object having the curved surface such as the inner/outer surface of a pipe without cutting the pipe or the like. SOLUTION: This radiation measuring device has a form wherein a radiation detection part 10 and a radiation measuring part are constituted separately, and both parts are connected by a cable 14. In the radiation detection part, a plurality of long and narrow plane-shaped radiation detection units 16 are arrayed in the width direction, and the radiation detection units are coupled detachably by a connection metal fitting 18 having a mounting part face-to-face angle corresponding to the surface shape to be measured. Measurement can be performed along the surface shape to be measured even in the case of a plane or an optional curved surface, by using the connection metal fitting having a different mounting part face-to-face angle.
