“…About a decade ago, there was great interest in dosimetry using the electron emitted when an irradiated material was heated. This method was reported to be quite sensitive for detecting gamma rays, and it was proposed that it could also be used for neutron dosimetry (Becker and Crase 1970). In the United States, interest in this dosimetry technique almost ceased when measurements (Gammage et al 1974) indicated that the neutron response in beryllium oxide was only about 11% of the photon response, and that the device would not be useful in mixed radiation fields.…”

“…The recoil proton "radiator" can be composed of either gaseous (e.g., an organic gas), liquid, or solid hydrogenous materials. There is a slight increase in the fast neutron sensitivity of this system from M.8 % at 100 keV, to ^28 % of the gamma radiation response at 16 MeV [13].…”

The poor stability of latent recoil proton tracks in photographic emulsions has frequently been underestimated due to unrealistic testing conditions. Thin polycarbonate foils to be evaluated by automatic spark-counting exhibit no fading for at least three months at 32°C and 95 % humidity. As one of several alternatives to the NTA film, optimized combinations containing 237 Np or' 232 Th and 10ym polycarbonate foils are described ( 237 Np covers a wide dose range of % 10" 3 to £ 10 rad, and neutron energies £ 0.6 MeV). The directional response is given for different neutron energies and detector-phantom distances. Another approach consists of the amplification of recoil nuclei etch pits to facilitate automatic counting. The inherently low fast neutron response of most solid-state detectors can be increased by intimate contact with a hydrogenous material. TSEE detectors based on BeO, for example, which are covered with a hydrogenous radiator, have been used successfully in recent tests of criticality monitoring systems at ORNL. The thin sensitive layer of exoelectron detectors makes this approach especially attractive for intermediate neutron energies.
