Characterization of Real-Time Neutron Dosimeters and Application to Aircrew Dosimeters

Overestimation of neutron doses at aviation altitudes have been induced from direct detection of cosmic protons but we found this overestimation could be due to high-energy neutron detections. We conducted experiments and simulations of response functions of neutron dosimeters. The experiments and simulations were done using mono-energy neutron sources produced by the accelerators, and using the Monte Carlo code, respectively. In the simulation, we added new energy deposition model, considering the Funneling phenomena. From our results, we will measure accurate neutron doses.
