为了建立一种测量内墙漆防氡效率的有效测量方法,采用局部静态法测量被测介质表面在测量期间的平均氡析出率。用有机玻璃制成充氡箱,用市售单面光滑的纤维板制作样品,用特制的PCMR-1连续测氡仪作测量手段,用GD-LI流气式固体氡源向充氡箱充氡,从而建立了内墙漆防氡效率的测定方法,该方法对不同内墙漆防氡效率容易实现同条件测量,测量结果具有很好的可比心。该方法能够满足内墙漆防氡效率测定工作的需要。%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 compared very well. The method can meet the need of radon mitigation efficiency measurement for interior wall paint.
