Review of nuclear techniques in subsurface geology

Nuclear techniques used to obtain data on geological strata require detailed analysis to understand the meaning of the measurements because of the extended region of the interactions and the complications introduced by the borehole environment. In addition, the nuclear parameters that are measured must be related to the geological parameters that are of interest. Types of measurements that can be performed, their relationship to geological parameters, limitations imposed by the need to make measurements in extended media under hostile conditions, and methods to analyze the measurements are presented.<>
