摘要
本文报道作者在气球法测氡应用中积累的有关相对湿度对其影响的数据和为此目的所作的一些实验研究的主要结果。结果表明,气球法测氡计数随相对湿度的增加而明显增加。文中强调在相对湿度变化较大的地表大气中应用气球法时,需了解当地的相对湿度变化范围,并用实验测定不同相对湿度下的刻度系数;即使在相对湿度变化较小的矿井下,亦宜按不同深度的采掘段,分别测定相应的刻度系数;且均应定期刻度。
This paper presents the data obtained on the effect ofrelative humidity on radon measurement by balloon method and someresults of experimental studies.The results show that the counting ofmeasuring radon by balloon method increases apparently with increasingrelative humidity. The paper emphasiges that when using the balloonmethod in surface atmosphere with higher relative humidity,the range ofrelative humidity is needed to understand, and the calibration coefficentunder different relative humidity should be determined.Even in the minewith minor variation of relative humidity,the calibration coefficientshould periodically be determined in accordance with the excavationsections with different depth.
