Abstract of the Disclosure A technique is provided for assaying the formations surrounding a borehole for uranium. A borehole logging tool cyclically irradiates the formations with neutrons and responds to neutrons during the period of time that prompt neutrons are being produced by the neutron fission of uranium in the formations. A borehole calibration tool employs a steady-state (continuous output) neutron source, firstly to produce a, response to neutrons in models having known concentrations of uranium and, secondly, to produce a response to neutrons in the formations surrounding the borehole. The neutron responses of the borehole calibration tool in both the model and the formations …
