title: The determination of trace amounts of natural 133Xe in gas under high radon activity concentration levels.
abstract: Radioxenon monitoring has become one of the major concerns in both international monitoring systems and on-site inspection. The most important technical specifications for radioxenon system are the radon removal coefficient and the minimum detectable activity concentration. We have developed one kind of on-site radioxenon sampling, separation and measurement system, and have tested it under high radon activity concentration levels. The result shows the natural (133)Xe background activity concentration, the (133)Xe/(222)Rn ratio and the radon removal coefficient to be in the ranges 0.73-1.6 mBq/m(3), (1.5-3.5) × 10(-8) and (2.3-57) × 10(-8), respectively.
