Comparison of gamma-ray coincidence and low-background gamma-ray singles spectrometry

Applied Radiation and Isotopes, 2012
Aerosol 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, 2010
The 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, 1968
Lithium-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 ...

AN IN SITU GAMMA-RAY SPECTROMETRY INTERCOMPARISON

Health Physics, 2003
This 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.

Uncertainties in gamma-ray spectrometry

Metrologia, 2015
High 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 ...

Gamma-Ray Spectrometry

2004
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.
