ABSTRACT:
A gamma ray detector for borehole logging includes a bismuth germanate crystal having a sensitivity to gamma rays and giving off light energy proportional to the energy of detected gamma rays. The bismuth germanate crystal is mounted in a housing which allows the operating temperature of the crystal to be maintained under increasing borehole temperature with depth.
