4.Chinese government,in 2002,promulgated and implemented the standards for controlling exposure to cosmic radiation of air crew GBZ 140—2002.This paper introduces the dose rate evaluation of cosmic radiation at the flight altitude and several common measurement methods and compares their calculations and results.
5.According to the dose limits for occupational irradiation recommended by International Commission of Radiological Protection,and fuking account of that cosmic radiation received by air carrier crew members was of long term and even distributed,authors suggest that,corresponding dose limit for crew members be revised and a series of protective measure be taken.
