A mixture of ZnS (Ag) and B/sub 2/O/sub 3/ was investigated with an aim toward using it for detection of thermal and resonant neutrons. The ratio of the ZnS (Ag): B ranging fron; 8:1 to 12:1 is optimum from the point of view of the efficiency with respect to neutrons, and of the form of the integral spectrum. The best thickness of the layer of the mixture is 0.75 to 1.0 mm. For these optimum values, the efficiency of the mixture with respect to neutrons is 25% at a low background of gamma rays. At a strong background of gamma rays, it is possible to reduce the background to 10/sup -7% with the aid of a discriminator, and the efficiency for neutrons remains not less than 5%.
