我们在铀矿区调工作中,试用水系底沉积放射性测量(U、~(210)P。)方法提供铀矿区域评价信息,取得了较好的效果。实践结果说明,在两万多平方公里的区调面积上,运用该方法可以快速缩小靶区。但是目前采用的U、~(210)Po分析方法的精度比较低,应研究和采用新的快速分析手段,并运用其他方法探测底沉积样品中铀系的其他元素,以多参数多信息提高该方法应用效果和解释评价水平,使之在区调中发挥更大的作用。
In the uranium mining project, we tried to use the bottom sediment radioactivity measurement (U, ~ (210) P) method to provide uranium mine area evaluation information and achieved good results. The practical results show that the method can be used to quickly narrow the target area over the area of more than 20,000 square kilometers. However, the accuracy of the U (210) Po method currently used is relatively low. New and rapid analytical methods should be studied and used, and other methods for detecting other uranium series elements in the sediment samples should be used. The multi-parameter and multi- The method applied the effect and explained the level of evaluation, making it play a greater role in the area adjustment.
