本文介绍一种放射性测井方法,其特点是,除了测量孔中的γ辐射外,同时还记录天然β辐射。此方法较为完善,因为用它可以直接测定实际上是纯β放射体的铀含量,而与矿石中的镭含量及其平衡情况无关。用此种方法可以测定不平衡铀矿石和平衡铀钍矿石中铀的真实铀含量而不是当量含量,而仅用一种γ测井方法是不能实现的。这种方 This article describes a radioactive logging method characterized by the addition of natural beta radiation in addition to the gamma radiation in the hole. This method is more complete, because it can be used directly to determine the uranium content is actually pure beta emitters, but with the ore in the radium content and its balance has nothing to do. This method can be used to determine the true uranium content rather than the equivalent content of uranium in unbalanced uranium ore and balanced uranium-thorium ores, which can not be achieved by using only a γ-logging method.
