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 ...

Underground gamma-ray spectrometry:
, 2006 Gamma-ray spectromety using high purity Ge detectors has made significant advances in recent years because large crystals have become readily available and the importance of very radiopure materials in the construction of dectectors has been understood ...

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 ...

On line gamma-ray spectrometry at open sea
Applied Radiation and Isotopes, 2005Set up and application of a stationary monitoring network for measuring specific gamma- activities in the Aegean Sea are described. Three NaI scintillator based spectrometers have been used to detect the gamma rays. The gross counting rate of each system was found to be nearly constant, when there was no rainfall. The volumetric activity of the natural

A dedicated LIMS for routine gamma-ray spectrometry
Applied Radiation and Isotopes, 2014We developed a Microsoft(®) Access-based LIMS (Laboratory Information and Management Systems), γ-LIMS, for the management of our gamma-spectrometry laboratory, in which thousands of routine, but high-quality analyses are performed each year. This paper explains the main features of the γ-LIMS and puts special attention on the interfacing methods and ...

Calculation of the decision thresholds in gamma-ray spectrometry
Applied Radiation and Isotopes, 2014A method was developed for calculating the decision thresholds for gamma-ray spectrometric measurements. At the energies where gamma-ray emitters that are present in the nuclide library, but were not identified in the spectrum, radiate, peaks are supposed to appear.

Radon gamma-ray spectrometry with YAP:Ce scintillator
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2002The detection properties of a YAP:Ce scintillator (YAlO3:Ce crystal) optically coupled to a Hamamatsu H5784 photomultiplier with standard bialkali photocathode have been analyzed. In particular, the application to radon and radon-daughters gamma-ray spectrometry was investigated.

Linssi: Database for gamma-ray spectrometry
Journal of Radioanalytical and Nuclear Chemistry, 2008Linssi is a Structured Query Language (SQL) database for HPGe gamma-ray spectrometry. It covers the whole production chain from sample preparation to final analysis results. Static or mobile sampling and measurement and multiple sample types are supported. In addition, each sample can be split or combined any number of times.

Coincidence summing of X- and gamma-rays in gamma-ray spectrometry
2007A new method for theoretical calculation of coincidence summing of X- and gamma rays for germanium spectrometers has been presented. The counting rate equations, derived by this method, enable to determinate peak efficiencies as well as the activity of the source.
