To develop a effective measurement method of radon mitigation efficiency for interior wall paint. By using a local static method, the average radon flux rate of a measured material surface during the period of monitoring can be gotten. The method has been developed using organic glass to make radon conmuliation chamber, lint board with a single smooth surface to make samples, PCMR-1 continuous radon monitor and GD-LI gas-through solid radon source. The same measurement conditions can be realized easily and the measurement results can be compar...
