The design of calculation for double spherical detectors of a neutron survey meter was introduced. The neutron energy responses of two moderators were simulated by MCNP3B program. A correction factor was determined due to a difference response of neutron energy for two moderators. The estimation of H*(10) was corrected so that the neutron energy response was improved. The relationship between distance of two moderators and angle response were calculated as to the influence of double spherical detectors, and the influence on factors was analyzed.

The monitor of neutron personal dose to professional worker become more and more important with the development of nuclear industry, nuclear plant and nuclear radiation cure. The design and calculation of TLD-albedo personal dosimeter were taken by using MCNP-3B Monte Carlo code. After the present of neutron and photon fluence response, the method to determine the field correction factor was introduced. The calculated results showed that TLD-albedo personal dosimeter could work well for photon with energy: from 33 keV to 1.5 MeV and for neutron with energy from thermo-neutron to 10 MeV, and corresponding energy response deviation could be less than 30% and 60% respectively.
