Application of <sup>10</sup> B Counter with Moderator for Neutron Ambient Dose Equivalent Measurement in Radiation Monitoring at JINR
The possibility to use the instrument based on the <sup>10</sup>B-counter (CHM-14) with polyethylene moderator as a dosimeter of the neutron ambient dose equivalent <i>Н</i>*(10) in the field of nuclear installations of JINR was investigated. It was shown that the instrument can be used to measure <i>Н</i>*(10) of neutrons in the energy range from 0.4 eV to 20 MeV with the uncertainty within 30% due to the dependence of response on neutron energy. The use of the correction factors can extend the energy range of measurement of the neutron dose <i>Н</i>*(10) up to hundreds of MeV. The uncertainty due to angular dependence of the instrument response is not more than 35%.
