Abstract: Since the Comprehensive Nuclear-Test-Ban Treaty (CTBT) was assigned in 1996, great progress has been achieved in China in all fields of verification techniques. As the only technique which can provide confirmative evidence of a nuclear explosion, radionuclide verification has been paid more attention. Aerosol and xenon samplers were developed to meet the qualification of CTBT together with the nuclide measurement techniques, and the national nuclide laboratory has been established. These developments assure China to carry the obligation in CTBT and improve its capability to guard the territory and environment of China. Also the techniques developed will play important roles in emergency monitoring in case of nuclear event and nuclear accident. In this review, the development of radionuclide verification techniques and the main achievements are outlined, and the future scopes of research are prospected.
