Description
The amount of radioactive impurities contaminated in the detector gases is required to be kept at a very low level for rare event particle physics such as dark matter search experiments. Zeolite is one of the possible candidates for removing radon and impurities from gases. A development of a new ultralow radioactive zeolite as a product of the selection of ultralow radioactive materials is reported. Results on the radon removal from argon gas and air are shown. Also, the results of more efficient radon adsorption tests with silver zeolite will also be reported.
