室内氡浓度主要决定于室内表面平均氡析出率、室外氡浓度及换气率这三个参数.该文建立了室内氡浓度与室内表面平均氡析出率关系的模型；在不同换气率及室外氡浓度条件下，计算了室内表面平均氡析出率的上限使得室内氡浓度不超过100Bqm－3.对中国南、北地区室外空气氡浓度，年平均换气率进行分析后，计算得到的室内表面平均氡析出率阈值可以统一定为31 Bq．m－2．h－1.该文还分析了累积法快速测量氡析出率的方法，提出要准确测量积氡罩内的氡浓度的变化规律，现有的静电收集法测氡仪需要提高测量精度，减少统计涨落.

The indoor radon concentration determined by three parameters:the average radon exhalation rate from indoor sur-face,the outdoor radon concentration and ventilation rate.In this paper,we proposed the model to describe the relationship be-tween the indoor radon concentration and the average radon exhalation rate from indoor surface.We calculated the requirements of the average radon exhalation rate from indoor surface under different ventilation rates and outdoor radon concentrations for limiting the indoor radon concentrations not to exceed 100 Bqm-3 .Analysis of the average outdoor radon conc...
