Based on a brief review of the development history and an analysis of the present situation of airborne radioactivity survey technology in China, this paper points out that a complete system of airborne radioactivity survey technology has been formed in China. By making a systematic and comprehensive summary of the major progress and technological innovation achievements of airborne radioactivity survey in China over the past 60 years, the authors believe that the research and development of airborne radioactivity instrument and the technical level have reached the international advanced level, and the technological innovation achievements have been expanded from mineral exploration to engineering geology, hydrogeological survey, environmental investigation, monitoring and some other fields. This paper discusses the main directions of airborne radioactivity survey technology development, summarizes the main problems that are exposed in practical work, and puts forward some suggestions for further work which have a certain guiding significance for uranium exploration based on airborne radioactivity survey as well as for investigation and planning of basic geological and environmental work in China.
