AN IN SITU GAMMA-RAY SPECTROMETRY INTERCOMPARISON
Health Physics, 2003This paper provides the results of an in situ gamma-ray spectrometry intercomparison that was held from 18-21 October 1999, in Grand Junction, CO. This intercomparison was a collaborative effort between the U.S. Department of Energy's Environmental Measurements Laboratory and the U.S. Environmental Protection Agency's Office of Radiation and Indoor Air.

The basic equipment for detection of prompt gamma rays is the gamma-ray spectrometer. The main component is the detector which converts the energy of the gamma ray to an electronic signal. This signal is amplified, shaped, digitized and stored in a histogram that makes up a spectrum of gamma peaks.

Principles of UV–gamma coincidence spectrometry
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2012Abstract With conventional methods, samples containing alpha-particle-emitting nuclides are difficult to detect and characterize from distances greater than a few centimetres. One promising technique is to observe alpha particles indirectly by utilizing alpha-induced ultraviolet (UV) photons.

Gamma-ray spectrometry by the method of pulse-height analysis makes possible the direct determination of individual radionuclides in a gamma-emitting sample. Such determinations are possible because the method provides a basis for the identification of specific nuclear transitions, and these, in turn, are characteristic of specific radionuclides.

Geological applications of gamma-spectrometry
International Geology Review, 1965A rapid indirect method for determining the radioelement content of rocks is furnished by the method of gamma spectrometry By measuring the energies of X-rays the concentrations of radium, thorium, and potassium can be estimated. This paper presents the theory of this method, its limitations factors affecting accuracy, and illustrates applications of ...

In-situ gamma spectrometry in environmental monitoring
Applied Radiation and Isotopes, 2010In-situ gamma spectrometry (scintillation or semiconductor) can be used effectively for monitoring natural and man-made radionuclide concentrations, together with the corresponding photon fields, in the environment and in workplaces. It is applied in operational and emergency monitoring of nuclear facilities, waste storage facilities and the uranium ...
