Abstract

Electronic Personal Dosemeter (EPD) was examined for effectiveness in cosmic radiation dosimetry at aircraft altitude through the measurements in a Japan-US round trip. The EPD value (H_epd) of individual dose equivalent, penetrating, H_p (10), was considered to be almost equal the deep absorbed dose attributed to electrons at the aircraft altitude. By assuming the fractions and the effective quality factors for other components (muons, protons, and neutrons) based on model-calculation data, an empirical equation to estimate a conservative deep dose-equivalent at 5 cm-tissue depth, H (50), was given as H (50) =3.1×H_epdEstimated H (50) values in the international flights were 4.9μSvh^-1from Tokyo to New York and 3.6μSvh^-1from Los Angeles to Tokyo. These values agreed well with the predicted values presented by NCRP.
