Neutron activation probe

Creators

Description

A neutron activation probe comprises a pulsed neutron source in series with a plurality of delayed neutron detectors for measuring radioactivity in a well borehole. The neutron source emits neutrons which produce fission in uranium in the ore body and the delayed neutron detectors measure the delayed 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 neutron detector from a particular ore zone may be added thereby increasing the accuracy of the reading corresponding to that ore zone
