PULSER STABILIZING IRRADIATION BEAM DETECTOR

摘要

A radiation detector useful for well logging and other applications contains a stabilizing pulsar device comprising a scintillator coupled to a photodetector and including a radio-active source such as an Am241 which simultaneously emits gamma rays and low energy particles such as alpha or beta particles upon decay. The pulsar device is coupled to the radiation detector which utilizes a scintillation crystal and photodetector, and the outputs from the two photodetectors are processed through a coincident/anti-coincident gate alternately to stabilize the gamma rays or to read the environmentally induced radiation.
