【摘要】：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。
[Abstract]:Based on the activated carbon-纬 spectrum method, the active carbon sampling device with different bottom area, height and effective contact area between the activated carbon and air was studied. The experimental results show that the effective contact area between activated carbon and air in the sampling device will affect the reliability of the sampling device, and under the condition of sufficient effective contact area, the bottom area, The relative error between the sampling device and the reference value is not greater than 5. This study can provide reference for the design of sampling device for measuring radon exhalation rate on different media surfaces.
