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.

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.

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 ...

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.

Techniques of field gamma-ray spectrometry
Mineralogical Magazine, 1981AbstractField gamma-ray spectrometry is a rapid and effective quantitative method of mapping variations of radioelements within igneous intrusions. A field procedure for radioelement mapping demonstrates the value of the method to studies of late-stage magmatic processes during the emplacement of granite intrusions and the determination of their ...
