The spectrum weighted responses of various detectors were calculated to provide guidance on the proper selection and useof survey instruments on the basis of their energy response characteristics on the neutron fields. To yield the spectrumweighted response, the detector response functions of 17 neutron-measuring devices were numerically folded with each of theproduced calibration neutron spectra through the in-house developed software ‘K-SWR’. The detectors’ response functionswere taken from the IAEA Technical Reports Series No. 403 (TRS-403). The reference neutron fields of 21 kinds with 2spectra groups with different proportions of thermal and fast neutrons have been produced using neutrons from the 241Am-Besources held in a graphite pile, a bare 241Am-Be source, and a DT neutron generator. Fluence-average energy (Eave) varied from3.8 MeV to 16.9 MeV, and the ambient-dose-equivalent rate [H*(10)/h] varied from 0.99 to 16.5 mSv/h.
