Abstract : The response of various infrared detectors to a pulse of nuclear radiation was analyzed theoretically and experimentally. The detectors studied included photoconductive lead sulfide, leadselenide and gold-doped germanium detectors, as well as an indium-antimonide photovoltaic junction detector. The lead sulfide and lead-selenide detectors were operated at room temperature; the others were tested at liquid nitrogen temperature. On an absolute basis, the detector which was most sensitive to radiation was gold-doped germanium and the least sensitive was lead selenide. However, the radiation-induced signals were of the same order as the infrared sensitivity; hence, witho t comparing in detail the infrared and radiation response, it is impossible to conclude which of these detectors would be most satisfactory in a radiation environment. Since the mechanisms responsible for the radiation response and those occurring during infrared excitation are quite similar, this rough correspondence between radiation sensitivity and infrared sensitivity is not surprising.
