摘要：
In order to study neutron dose measurement in high energy radiation field, a Dual-moderated survey meter in the range from 1 key to 300 MeV mean energies spectra has been developed. Measurement results of some survey meters depend on the neutron spectra characteristics in different neutron radiation fields, so the characteristics of the responses to various neutron spectra should be studied in order to get more reasonable dose. In this paper the responses of the survey meter were calculated under different neutron spectra data from IAEA of Technical Reports Series No. 318 and other references. Finally one dose estimation method was determined. The range of the reading per H*(10) for the method estimated is about 0.7-1.6 for the neutron mean energy range from 50 key to 300 MeV.
