Airborne survey is being paid more and more attention in the nuclear and radiation environment monitoring due to its unique advantages,especially after the nuclear accident of Fukushima Japan.Thus,National Nuclear Safety Administration is strengthening to build airborne survey capacity.The administration has set up an advanced airborne survey system and established an expert team.This airborne survey system here is fixed under a capable helicopter,which has a monitoring volume of 75.6 liters,independent advanced digital spectrometer and intelligent data processing functions.In this paper,a way that is applied for wireless data real-time transmission is presented,and our research works on calibration and the survey methods are also included.The airborne survey system can be widely used in the nuclear and radiation accidents monitoring and relative radiation monitoring in NORM.
