"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. " - How gamma ray spectrometry is work

Web16 feb. 2024 · The spectrometer is also capable of providing results on light intensity. However, this requires using multiple complex formulas to calculate the object or sample’s transmittance. Spectrometers measure a wider range than visible light, which represents just a fraction of the wavelengths of light. 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.
