Gamma ray measurement
WebThe Hostile Environment Natural Gamma Ray Sonde (HNGS) utilizes two bithmus-germanate (BGO) scintillation detectors to measure the natural gamma ray radiation of the formation. The larger detector volume and higher gamma ray stopping power of BGO makes the HNGS a very effective spectral gamma tool. WebThe gamma-ray given off has a distinct energy associated with the atom from which it was released. In essence the gamma-ray emitted is like a “fingerprint” of the element. The emitted gamma-rays are detected and an energy spectrum generated which can then be analyzed for elemental composition. ... uniform measurement of the entire material ...
