N2 - A new type of alpha-particle imaging system was constructed to reduce the time required for detecting plutonium contamination. The imaging system consists of a ZnS(Ag) screen, two tapered fibers, an image intensifier, and Polaroid film. Spots due to single alpha-particles can easily be obtained on the Polaroid film. The observed spatial resolution is more than 3 lp/mm. This system requires about one-seventh of the exposure time required by ZnS(Ag) autoradiography in order to distinguish between plutonium contamination and radon and thoron daughter products.
