Three types of radiation detectors that were successfully used in reactor physics experiments are described in terms of design and performance characteristics. The first is a neutron-sensitive ionization chamber used for pile oscillator measurements with the critical assembly ANNA. It is a gamma- compensated chamber. Boron is fused to the aluminum electrode. The second type of detector is a fission counter lined with natural uranium, and its counterpart, lined with uranium enriched in U/sup 235/. The construction of this counter with its low sensitivity and small diameter makes it uniquely suitable for flux- mapping along the length of a reactor's access port. The third detector is a miniature ionization chamber for gammas. It is an air-filled ionization chamber with active volume of l4 cm/sup 3/, a sensitivity of 10/sup -12/ amp/r/hr and a linearity up to 3 x 10/sup -7/ amp with the collector voltage at 600 volts.
