摘要
本文研究了一种对环境空气中微量氡的测量方法,应用活性碳吸收管进行浓集采样,加热解析后测量放射性。吸附效率在25℃约90％,在10℃约98％。解析效率99.6％。本法方便实用,测定误差小于10％,在一般情况下约为5％。
A method for the determination of trace radon in ambient air was described. In this method the trace of radon was absorbed and concentrated by an active charcoal adsorbing tube, then the activity of radon was measured after deadsorbing. The efficiency of adsorbing is about 90％ at 25℃ and about 98％ at 10℃. The efficiency of deadsorption is 99.6％. This method is rather convenient and practecal. The error of this method is below 10％, generally about 5％.
