Abstract: Because the energy response performance of neutron dose-equivalent meters with single detector is not very good, a new type of neutron dose-equivalent meter was designed. Its detector composed of two spheric moderators with different thicknesses and two spheric 3He proportional counters. The energy response of two spheric 3He proportional counters embeded into the centers of the moderators were calculated by the use of MCNP codes. In order to get the ambient dose-equivalent results, the ratios of the counts were used to get a factor to correct the conversion of the counts to amibent dose-equivalent. With theory analysis and experiment validation, it shows that the energy response performance of the neutron dose-equivalent meter is improved obviously. The response of neutron energy from thermal to 14 MeV can be narrowed to a range of 0.7-1.3.
