| 内容記述 | Although it is important to know accurately energy spectra of energetic neutrons (>10MeV) for radiological protection of aircraft and spacecraft crew, dosimetry of cosmic radiation at aviation altitude is still difficult because signals from charged particles such as protons and heavy ions are mixed with those from neutrons. We thus try to develop a portable detector which can measure separately energetic cosmic components (neutrons, protons, muons, electrons and gamma rays). For testing the feasibility of our concept, experiments of cosmic radiation measurements were performed in a jet aircraft using various detectors (scintillation counters, dose-equivalent counters and an ionization chamber). The aircraft flew on two routes (north/south) over the Japan sea in March, 2007; the flight duration was about 2h each. The measured data were compared to model calculations using a new PHITS-based analytical model. As results, the measured values of a combined scintillation counter and an extended energy range dose equivalent counter show fairly good agreement with model predictions. This fact indicates that the new model can be adequately used for the assessment of cosmic radiation exposure of aircraft crew, though it is desirable to verify neutron doses independently by separating them from cosmic protons in future measurements. | |||||
