A closed-loop stabilization system and method for a radiation detector system including a scintillator and a light sensing device for detecting the scintillation light produced in the scintillator through interaction with impinging radiation. A spectrally stable gamma ray measurement for downhole and other non-isothermal gamma ray measurement applications is obtained by use of a light source for emitting photons, preferably ultra-violet photons, into the scintillator that are not detectable by the light sensing device. The light source causes the scintillator to fluoresce at a wavelength detectable by the light sensing device, and the change in measured fluorescence is used to adjust system gain to account for variations in scintillator output attributable to environmental conditions. In this manner, the stabilization system adjusts the system gain to maintain consistency among radiation measurements over a wide temperature range.
A radiation detection system comprising:
A method of stabilizing the output of a radiation detection system which includes a scintillator for emitting flashes of light in response to radiation impinging upon the scintillator and a light sensing device positioned proximate the scintillator to receive the flashes of light, the light sensing device producing an electrical output having a magnitude correlated to the light produced by the scintillator, said method comprising:
