Abstract

See full text

An apparatus is provided which is capable of directly and efficiently measuring surface contamination of objects to be measured having curved surfaces such as inner and outer surfaces of pipes without the need for cutting pipes, etc. This radioactivity measuring apparatus comprises a radioactivity detection section 10 and a radioactivity measuring section 12 arranged separately and connected together via cables 14. The radioactivity detection section has a structure in which a plurality of elongated plate-shaped radioactivity detection units 16 are arranged in the width direction and connected together in a detachable manner using connecting fittings 18. Each of the connecting fittings is formed in such a way that it is bent at angles between surfaces of parts thereof on which the respective radioactivity detection units are mounted corresponding to the shape of the surface to be measured. Using the connecting fittings having different angles between mounting surfaces allows flat surfaces or even curved surfaces with arbitrary curvatures to be measured in conformity with the shape of the surface.
