Abstract :
A novel 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.<>
