| Abstract: | Various neutron detectors for spectrometry, environmental dosimetry and
personal dosimetry have been developed by our group. For high energy neutron
spectrometry, spallation detectors of C and Bi, large plastic and NE-213
scintillators, self TOF detector have been used for neutron production and
shielding experiments at several high energy accelerator facilities, ISIS of
Rutherford Appleton Laboratory, UK, Two-mile Linac of Stanford Linear
Accelerator Center, USA, HIMAC of National Institute of Radiological Sciences,
Japan, and RCNP of Osaka University, Japan. The response functions of these
detectors have been obtained by measurements and calculations. Thick target
neutron yields produced from high-energy particles from protons to Xe ions have
been summarized, together with shielding benchmark experiments through concrete
and iron at these facilities. Neutron measurements over wide energy range
including cosmic neutron field were done with Phoswich detector and Bonner
sphere spectrometer. For environmental neutron dosimetry, two types of dose
equivalent dosimeters, so-called rem counters, high-sensitive type and
light-weight type, have been developed and for personal dosimetry, silicon
semiconductor dosimeter has been developed for use in nuclear facilities. These
dosimeters have good quality to give ambient and personal dose equivalents for
neutrons in the mixed radiation fields. The outline of these works will be
reviewed in this paper. |
