1.概况柳湖泉位于平凉城北的公园内,属第四系全新统出露的冷水泉,主要是泾河水和降雨补给。泉点水温年平均为12℃。氡含量为15埃曼。使用的观测仪器是FD——125射气仪。2.水氡变化形态用五年水氡的月均值作为纵坐标,时间(月)作为横坐标作图。从图1中可以看出尽管每年的水氡值有差异,但变化趋势基本一致。即每年十二月到第二年一、二月份是氡值最低阶段,七、八月份是氡值最高阶段,整个变化图形呈正弦形曲线。 1. Overview Liuhuquan is located in the park north of Pingliang, a Quaternary Neolithic cold water spring is exposed, mainly Jinghe water and rainfall supplies. Spring water temperature average of 12 ℃. Radon content of 15 Aman. The observation instrument used was a FD-125 radiometer. 2. Water radon change patterns with five-year average monthly water radon as the vertical axis, time (month) as abscissa mapping. It can be seen from Figure 1 that although the annual water radon values ​​are different, the trend of change is basically the same. That is, from December to the second year of each year, February and February are the lowest levels of radon. In July and August, the highest level of radon is the highest, and the entire graph shows a sinusoidal curve.
