| 摘 要： | 应用氡气所测量,特别是静电α卡法,找寻基岩地下水和地热,解决工程地质有关问题,在我国取得了明显的效果.我们研究的静电α卡法是一种累积测氡技术,它具有灵敏度高,成本低,能在浮土覆盖厚,电磁干扰及噪声干扰严重,地形起伏大的山区、城镇工作,为开展水工物探、城市物探等提供了一种有效的物探方法.自82年以来,应用静电α卡法曾在我国廿多个省市,上百个地点进行过找水、找矿、找石油、解决工程地质问题、进行地质填图、考古等试验.结果表明,静电α卡法等测氡技术具有良好的地质效果与经济效益.

| Abstract: | In china, remarkable achievements have already been attained in using radon measurement, especially electrostatic alpha-card method, for groundwater and geothermal prospecting and for engineering geology.weak anomalies of radon usually exist near geological structures containing underground water or geothermal water along fracture zones. The reason is that these structures usually related to some factors affecting the distribution of ra dioactive elements, such as the change of lithologic characters, the rupture of rocks and the high radon content in geothermal water. These structures can therefore be found through detecting the faint radioactive anomalies.The electrostatic alpha-card method invented by the authors is one of the techniques for radon measurement. It has high sensitivity, requires low cost,and is seldom disturbed by topography and other surface features. Hence, it can be used in areas with thick regolith or serious electromagnetic disturbance or noise disturbance, such as cities or town, mountains, factories and mines. The electrostatic alpha-card method serves as an effective and economical method in hy-drogeophysical and engineering geophysical exploration and municipal geophysical exploration.Since 1982, experimental work of electrostatic alpha-card method has been conducted at over 100 places in more than 20 provinces to search for uranium, gold, oil and gas, to detect the leakages of reservoirs, to investigate vein rocks, to delineate boundaries of different rock bodies, and to seek for groundwater and geothermal water. Facts show that this radon-measuring technique yields good geological results snd economic benefits. |
