Open-faced charcoal canisters have been used for radon measurements for over 40 years. This method is sensitive to temperature, changing radon concentrations, humidity and other parameters, but a comprehensive study dealing with the influence quantities and measurement uncertainty was not available in literature. In this paper, all the identified influence quantities are discussed in detail, uncertainty budget is developed, good practice and bad practice examples are introduced and new recommendations are proposed to optimize the method and reduce uncertainty.

使用敞口木炭罐进行measurements测量-测量不确定度和方法优化。

敞开的木炭罐已用于测量ra，已有40多年的历史了。该方法对温度，变化的changing浓度，湿度和其他参数敏感，但是在文献中尚无关于影响量和测量不确定度的综合研究。本文详细讨论了所有已确定的影响量，制定了不确定性预算，介绍了良好实践和不良实践实例，并提出了新的建议以优化该方法并减少不确定性。
