Comparison of gamma-ray coincidence and low-background gamma-ray singles spectrometry
Applied Radiation and Isotopes, 2012Aerosol samples have been studied under different background conditions using gamma-ray coincidence and low-background gamma-ray singles spectrometric techniques with High-Purity Germanium detectors. Conventional low-background gamma-ray singles counting is a competitive technique when compared to the gamma-gamma coincidence approach in elevated ...

Traceability in gamma-ray spectrometry
Applied Radiation and Isotopes, 2010The new edition of the International vocabulary of metrology-basic and general concepts and associated terms (VIM) defines metrological traceability in a different way than was defined in the previous edition. The reference to an "unbroken chain of comparisons" is replaced by a "chain of calibrations." Calibrations, unlike comparisons, render possible ...

Ge(Li) gamma-ray spectrometry as a pilot for NaI(Tl) gamma-ray spectrometry
Talanta, 1968Lithium-drifted germanium semiconductor detectors give much better resolution than do thallium-activated sodium iodide detectors, but much lower sensitivity. They can often advantageously be used in conjunction with NaI(Tl) detectors, to show whether corrections must be applied for activities other than the one to be measured and to provide the ...

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.

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.

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.

Uncertainties in gamma-ray spectrometry
Metrologia, 2015High resolution gamma-ray spectrometry is a well-established metrological technique that can be applied to a large number of photon-emitting radionuclides, activity levels and sample shapes and compositions. Three kinds of quantitative information can be derived using this technique: detection efficiency calibration, radionuclide activity and photon ...

Determination of the measurement threshold in gamma-ray spectrometry
Applied Radiation and Isotopes, 2017In gamma-ray spectrometry the measurement threshold describes the lover boundary of the interval of peak areas originating in the response of the spectrometer to gamma-rays from the sample measured. In this sense it presents a generalization of the net indication corresponding to the decision threshold, which is the measurement threshold at the ...
