【摘要】：基于活性炭-γ譜法,對(duì)底面積、高度、活性炭與空氣的有效接觸面積不同的活性炭采樣裝置進(jìn)行研究。實(shí)驗(yàn)結(jié)果表明:活性炭在采樣裝置中與空氣的有效接觸面積大小會(huì)影響采樣裝置的可靠性;在有充足有效接觸面積的條件下,底面積、高度不同的采樣裝置與參考值相對(duì)誤差不大于5%。該研究可為不同介質(zhì)表面氡析出率測(cè)量的采樣裝置設(shè)計(jì)提供參考。
[Abstract]:Based on the activated carbon-緯 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.
