Some aircrews are certainly anxious about exposure to cosmic radiation. It is thus desired for experts of radiation protection to offer relevant correct information such as route doses and the health effects of low-dose radiation, so as not to make those concerned to suffer from excessive anxiety. In the present study, effective doses on round-trip flights from Tokyo's New International Airport (Narita) to major cities in the world are calculated under conservative conditions. Based on the calculation results, a method for screening the aircrews that need radiation exposure management is discussed.
