讨论了放射性曲线与所研究地层物理性质的关系，包括所涉及岩石历史的影响。对不同类型地层中相关层的可能面积范围进行比较，并将各种测井方法区分这些层的能力作为各种测井方法地质有用性的指标。讨论了区分与邻近岩石（如断层和不整合面）没有明显物理差异的蚀变带的可能性，并考虑了其与放射性测井的有效性的关系。给出了放射性测井曲线相关功率的图解。通过与电测井和地质样品测井的比较来说明所讨论的问题。简要讨论了放射性测井方法和野外作业技术的发展情况。
A discussion of the relation of radioactivity curves to physical properties of strata studied, including the influence of the history of the rocks involved. Comparisons are made between the probable areal extent of correlatable horizons in various types of formations, and the ability of various logging methods to distinguish these layers is considered as an index of the geological usefulness of the various logging methods. The possibility of distinguishing altered zones which do not show marked physical differences fom the neighboring rocks (such as faults and unconformities), is discussed, and its bearing on the usefulness of radioactivity logging is considered. Illustrations of the correlating power of radioactivity logs are given. Comparisons with electrical logs and with geological sample logs are shown to illustrate the points discussed. A brief discussion of the development of the radioactivity logging method and of the technique of carrying out field operations is also given.
