Abstract
A borehole logging tool includes a source of fast neutrons and a fast neutron detector. A discriminator connected to the detector rejects pulses from the detector attributable to nonsource neutrons from the formation and passes to a count rate meter those pulses from the detector attributable to source neutrons. The output of the count rate meter is recorded as a measure of neutron source output.
