Main contents and conclusions are: 1 The ionization current was measured continuously by a charge-integration method with a computer after the introduction of radon into the chamber.
主要内容及结论:1充氡后利用计算机连续进行电离电流累积测量,得到了精细的电流随时间的变化曲线,可清楚看出氡及其子体的生成衰变造成的电离电流的生长—稳定—衰减过程,与理论计算值进行了比较,由电离电流衰减速度的变化得出氡吸附作用的影响,并测量到电离室冲洗后氡的反扩散现象;2由已知活度的标准源定出相对测量的刻度系数K值,K=24.62 Bq/pA,对同一个监测源以半年为周期进行多次测量后得出稳定性符合要求;3通过测量电离电流和气压的关系曲线以及不同气压下的饱和曲线,确定了常规的工作条件;4测量了盐酸清洗电离室内表面降低本底的效果;5不确定度分析表明相对测氡的扩展不确定度(k=2)小于5%,由本底涨落得出探测下限为0.5 Bq;6理论上对壁损失修正进行了计算,实验上保持电离室工作在饱和区的情况下,测量了不同气压下电离电流的变化,从中得出了壁损失随气压变化的规律,可以看出,电离电流的实测值和计算值随气压变化规律基本一致;当气压大于125 kPa时,端效应等其它因素造成的影响不大于2%,因而在此工作条件下,测量电离电流后通过计算修正壁损失可以实现近似的绝对测氡,提出了进一步提高绝对测量准确度的方法。
