Abstract

This paper investigates the removal of radon from purified and ambient airs by Ag-zeolite. Ag-zeolite is known to have very high performance in terms of airborne radon removal. The dependence on zeolite type and silver content of the performance of radon removal was evaluated. The performance of radon removal by a single pass and radon emanation were also evaluated. In addition, the adsorption performance due to zeolite solidification and the change in adsorption performance due to moisture in the gas were evaluated in order to investigate properties that should be considered for future practical use. These properties will be applicable to the development of air purification systems for large-volume ultra-low-radioactivity experiments.
