Abstract :
A nuclear survey instrument with an imaging capability is being developed for remotely locating high-level radioactive sources with minimal operator exposure. It combines an image of the distribution of radioactivity with a video image of the area containing the source. allowing rapid remote location of the source. The nuclear imaging system is based on a position sensitive photomultiplier tube and a diverging hole collimator. The design and measured performance of a prototype device are discussed
