A study on the necessity of boarding control for international flights

Abstract: It is certain that part of aircraft crew are anxious about exposures to cosmic radiation. It is thus desired for experts of radiation protection to offer reliable information such as route doses and health effects of low-dose radiation, so as not to let the crew suffer from excessive anxiety. Accordingly, effective doses received on major routes of international flights from the Tokyo/Narita airport are calculated under conservative conditions. Based on the calculation, a basic framework for controlling cosmic radiation exposures of aircraft crew is proposed. [Copyright &y& Elsevier]
