System for measuring the natural gamma radiation of surface and subsurface formations |
摘要 |
A natural gamma radiation measuring system includes a gamma ray detector and a multichannel analyzer for recording a full gamma-ray energy spectrum. An artificial source of gamma radiation that is temperature insensitive provides a known level of gamma radiation which is utilized by the multichannel analyzer to provide gain stabilization for the full energy spectrum output of the gamma ray detector.
