Neutron activation probe

Description

A neutron activation probe comprises a pulsed neutron source in series with several delayed neutron detectors for measuring radioactivity in a well borehole. The neutrons from the source produce fission in uranium in the ore body and the delayed neutron detectors measure the neutrons produced from such fission while the probe is moved through the borehole. The signal from each neutron detector is delayed in time so that the activity measured by each detector from a particular ore zone may be added, thereby increasing the accuracy of the reading corresponding to that ore zone
