A pair of miniature proportional counters, one with graphite walls and one with walls of A150 plastic, were used to separate neutron and photon dose components in a mixed field. Data were simultaneously acquired for both counters in a combined field of 14.8-MeV neutrons and /sup 60/Co photons in three overlapping dispersions. A previously acquired /sup 60/Co spectrum in the graphite counter was used to normalize a mixed field spectrum, thereby determining the photon dose. This dose normalized a photon-only spectrum in the A150-walled counter, which was then subtracted from the mixed field spectrum. Comparison of these results to ionization chamber results is discussed.
