The Effects of Nuclear Radiation on High Temperature Thermistors

· IRE Transactions on Nuclear Science
High temperature thermistors, 100 to 600 deg C, were tested before, during, and after irradiatton, The radiation environment was held constant at 2.2 x 10/sup 10/ n/sub f//cm/sup 2/-sec (n/sub f/ = fast neutrons with energy >2.9 Mev) and 4 2 x 10/sup 8/ ergs/gm(C) hr GAMMA for a period of 91 hours. Resistance as a function of temperature was measured for high, medium, and low resistance type thermistors. No permanert damage was observed, but transient effects were severe at high resistance values. The transient effects were due to ionization of the air and the thermistor material by the nuclear enviromnent. The ionic conduction in the thermistor material was highly temperature dependent.
