An experiment involving neutron and gamma measurements in the irradiation volumes of the Radiation Effects Testing Facility for a dry-pool configuration was carried out. The purpose of the experiment was to map the radiation field in the region normally used for radiation-effects investigations. Each of the three inrradiation volumes constituting this region was mapped with detectors spotted in a minimum of 17 locations in each of the three rack positions. Neutron measurements were made with sulfur and cobalt detectors; gamma measurements were made with chemical dosimeters. The detectors were irradiated for 3 hr at a reactor power lever of 500 kw. The maximum fast neutron flux (E greater than 2.9 Mev) received was 7.1 x 10/sup 4/ neutrons/cm/ sup 2// sec-watt; the maximum thermal neutron flux, 2.3 x 10/sup 3/ neutrons/cm/ sup 2//sec-watt; and the maximum gamma dose rate, 2.8 x 10/sup -1/ ergs/g(C)/sec- watt.
