Analysis of the Exposure of Domestic Flight Crews to Space Radiation

Abstract

The purpose of this study is to compare and analyze the exposure dose of flight crew to space radiation. Flight selection was made from Gimpo Airport to domestic destinations of Jeju Island, Busan/Gimhae, Ulsan, Yeosu, Gwangju, and Daegu city. Dose measurements were based on the CARI-6/6M model developed by the Federal Aviation Administration and the Nowcast of Atmospheric Ionizing Radiation for Aviation Safety (NAIRAS) model, both developed by the Federal Aviation Administration. The results doses of 0.63 µSv at Jeju and 1.65 µSv at Busan/Gimhae based on the show NAIRAS model. The doses were 0.86 µSv (NAIRAS), 0.93 µSv, 1.03 µSv, 1.00 µSv fol destination of Yeosu, Ulsan, Gwangju, and Daegu, respective. Although there doses are light crews need to study appropriate safety management directions to protect themselves against space radiation, more over national standards and appropriate operational measures need to be established.
