Measurement of Cosmic Radiation Exposure on Flights of the Xinjiang Airline
New basic standard for the safety of radiation protection of China state that measures need to be taken for flight crewmembers whose annual radiation exposure exceed 1 mSv. The recommendation for the implementation of the basic safety standard state that for annual levels between 1 and 5 mSv individual dose estimates should be obtained. In 2004, cosmic radiation measurements were performed on a total of 21 flights of the Xinjiang Airline. The results show that the average effective dose rate of all flights of Xinjiang Airlines from September to November 2004 was 2.55μSv.h-1 (ranging between 1.39-4.90μSv.h-1). Average annual cosmic radiation dose on flight personnel was 2.65mSv.a-1 (ranging between 1.29-4.66mSv.a-1). Annual individual effective doses of all measured flight personnel are well below the limit 5 mSv.a-1 by basic safety standard of China.
