Calibration of Energy-, Dose-Response for High Sensitivity Neutron Dose Equivalent Rate Meter

Based on the corresponding standards of the National Standardization Organizations, the International Organization for Standardization and the International Electrotechnical Commission for neutron dosimetry calibration, the energy response of a well designed and manufactured neutron dose equivalent meter of high sensitivity which is of cylindrical type and large volume was calibrated on a wide energy range (from thermal energy to 20 MeV). The calibration methods, experimental program results and analysis were mainly introduced, and the comprehensive sensitivity of neutron dose equivalent 48.9 s－1/（µSv•h－1） as well as dose equivalent responses in three characteristic neutron spectrum fields were presented.
