The XMASS liquid xenon detector in the Kamioka mine in Japan is probing for WIMP Dark Matter candidates. Its sensitivity will ultimately be limited by the background levels that can be achieved in the experiment. Radon is of particular concern, as trace quantities of it will continuously emanate from materials in and around the detector. We describe the techniques developed in Kamioka to maintain the quality of the xenon in the detector and present the pertinent test results.
