It is known that the ratios of multiple detectors outputs and objective values compose closed convex in vector space forming with these ratios in the case of optimum obcective value evaluation, such as dose evaluation, with multiple radiation detectors. Neutron dose evaluation method with this method is discussed. A neutron detector with high sensitivity for thermal neutrons and fast neutrons combined was applied for dose evaluation experiment with this method. The response of the detector was simulated by calculation and experimentally validated with mono-energy neutron and RI. A vector space with tis detector was calculated. It is confirmed that the simulated outputs of detectors with various types of neutron field and experimental outputs plotted in this vector space are arranged in closed convex.
