研究了一种连续测量环境氡浓度的方法,该方法需确定前次测量对当次测量的影响,即迭代修正因子。推导了适用于上述连续测氡方法的迭代修正因子的理论公式,并计算了迭代修正因子的理论值。用基于上述方法研制的NRL-1型氡连续测量仪进行了迭代因子的测量,并对测量结果的影响因素进行了讨论。结果表明,理论计算结果与实验测量结果符合较好,迭代修正因子仅与取样时间和测量时间有关。

A method for continuous measurement radon in environment was developed. The method needs to determine the iterative correction factor about the contribution of one measurement to the next. Formulas of the theoretical iterative correction factor were derived and its values were calculated. Then iterative correction factor was measured by the NRL-1 continuous radon monitor based on the method, and the influence factors of measurement results were discussed. The result shows that the values of theoretical calculation are fundamentally consistent with the field measurement results, and the iterati...
