摘要
对湖南省宁乡铀矿井口废石堆表面氡析出率进行了历时一年的监测研究。监测结果表明:废石堆氡析出率年变化(一年内的逐月变化)有明显的季节性,呈冬季高、夏季低;日变化(一日内的逐时变化)呈白天低,夜间高的特征;降雨使氡析出率明显降低。
Abstract Radon exhalation rate from The results show a significant seasonal mer, and a diurnal variations, higher uranium mine waste rock surface was sutided for a year of time period. month variations in exhalation rate, higher in winter and lower in sumin night and lower in winter. Rainfall may result in a signifiacant reduction in exhalation rate.
