  2. Gamma spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Gamma_spectroscopy

    Gamma-ray spectroscopy is the qualitative study of the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics. Gamma-ray spectrometry , on the other hand, is the method used to acquire a quantitative spectrum measurement.

  3. Gamma-ray spectrometer - Wikipedia

    en.wikipedia.org/wiki/Gamma-ray_spectrometer

    A gamma-ray spectrometer (GRS) is an instrument for measuring the distribution (or spectrum—see figure) of the intensity of gamma radiation versus the energy of each photon. The study and analysis of gamma-ray spectra for scientific and technical use is called gamma spectroscopy , and gamma-ray spectrometers are the instruments which observe ...

  4. Multichannel analyzer - Wikipedia

    en.wikipedia.org/wiki/Multichannel_analyzer

    Sound cards have high-speed but low-resolution (up to 192 kHz) ADC chips, allowing for reasonable gamma spectroscopy performance for a low-to-medium count rate. [4] The "sound card spectrometer" has been further refined in amateur and professional circles. [5] [6]

  5. Spectrometry - Wikipedia

    en.wikipedia.org/wiki/Spectrometry

    Spectrometry may refer to: Optical spectrometry , a technique for measuring the distribution of light across the optical spectrum, from the ultraviolet spectral region to the visible and infrared Ion-mobility spectrometry , an analytical technique used to separate and identify ionized molecules in the gas phase based on their ion mobility in a ...

  6. X-ray fluorescence - Wikipedia

    A Philips PW1606 X-ray fluorescence spectrometer with automated sample feed in a cement plant quality control laboratory XRF scanning of the Rembrandt-painting Syndics of the Drapers' Guild. A Helmut Fischer(company) X-ray fluorescence spectrometer which are used to check for metals coating thickness and any of potential contamination of ...

  7. Total absorption spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Total_absorption_spectroscopy

    Total absorption spectroscopy is a measurement technique that allows the measurement of the gamma radiation emitted in the different nuclear gamma transitions that may take place in the daughter nucleus after its unstable parent has decayed by means of the beta decay process. [1]

  8. Scintillation counter - Wikipedia

    en.wikipedia.org/wiki/Scintillation_counter

    Measurement of gamma ray spectrum with a scintillation counter. A high voltage drives the counter which feeds signals to the Multichannel Analyser (MCA) and computer. Scintillators often convert a single photon of high energy radiation into a high number of lower-energy photons, where the number of photons per megaelectronvolt of input energy ...

  9. Nuclear forensics - Wikipedia

    en.wikipedia.org/wiki/Nuclear_forensics

    Gamma spectroscopy yields results that are conceptually equivalent to alpha-particle spectroscopy, however, can result in sharper peaks due to reduced attenuation of energy. Some radionuclides produce discrete γ-rays that produce energy between a few KeV to 10 MeV which can be measured with a gamma-ray spectrometer. This can be accomplished ...
