一、前言~(218)Po 法测氡自从1982年提出后,已经进行了两年多的实践。在野外实践中,得到了各生产单位的大力支持,同时也获得了他们的好评。它的特点,正如269大队十一分队总结的那样,“~(218)Po 法具有异常峰底比显著、干扰因素少、效率高、成本低、见效快和能马上运用于指导生产等特点。”今年五、六月间,在三0四大队六工区,用~(218)Po 法曾做了二十来条剖面的测量工作。对所发现的异常都进行了辨别和定量解释,其结果对生产有一定的指导意义。有的解释结果经钻探验证吻合较好。由于能对未知地段提出预测,使该队原来否定的一号带又得到了重新 I. Preface ~ (218) The Po method for measuring radon has been in practice for more than two years since its introduction in 1982. In the field of practice, has been the strong support of the production units, but also won their praise. Its characteristics, as summarized by Detachment 269, are that the “~ (218) Po method has the characteristics of unusual peak-to-bottom ratios, less disturbing factors, higher efficiency, lower cost, faster effectiveness, and immediate utilization in directing manufacturing. ”Between May and June this year, in the No. 6 Working Area of ​​the 340th Brigade, twenty or so profile surveys were conducted using the ~ (218) PoE method. The discovered abnormalities were identified and quantitatively explained, the results of the production of a certain degree of guiding significance. Some interpretation of the results verified by drilling better agreement. As a result of the prediction of the unknown lot, the band No. 1, which was originally rejected by the original team, has been renewed
