基于活性炭-γ谱法,对底面积、高度、活性炭与空气的有效接触面积不同的活性炭采样装置进行研究。实验结果表明:活性炭在采样装置中与空气的有效接触面积大小会影响采样装置的可靠性;在有充足有效接触面积的条件下,底面积、高度不同的采样装置与参考值相对误差不大于5%。该研究可为不同介质表面氡析出率测量的采样装置设计提供参考。

The text is based on active carbon- gamma spectrum method to research about some sorts of active carbon sample devices whose basal area, height, active carbon and air contact area are different. The experimental results show that the effective contact area of active carbon and the air in the sampling device can affect the reliability of the sampling device. In the condition of sufficient and effective contact area, sampling devices with different bottom area and different height are selected, the relative deviation between the measurement value...
