WebRegardless of the crystal type, a coaxial detector can be used for general gamma-ray spectroscopy purposes. For low energy gamma-rays below 100 keV, a significant portion of the incident photons is attenuated for p-type detectors due to the relatively thick surface dead layer, i.e. lithium n+ contact. Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics. Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced. WebGamma-ray spectrometry Photon spectrometry is a widely used nuclear measurement technique for identifying and quantifying X- and gamma-emitting radionuclides in any kind of sample. It is a non-destructive technique which does not require specific sample preparation. greenlin pet resorts hershey
