ABSTRACT
Results of analysis of cosmogenic radionuclides (Co, Mn, Sc, Na, V and Al) in fragments of the Košice meteorite are presented and discussed. Analyses were carried out using a low-level HPGe-spectrometer placed in a lead-iron-copper shield. Twelve meteorite fragments were available for the analysis with masses from 27 to 2,163 g. The lowest massic activities were observed for Sc (down to 0.1 mBq/g), and the highest for Na (up to 2 mBq/g). The measured radionuclide activities showed differences between fragments, as indicated mainly by the Co data, which were caused by different positions of meteorite fragments from the center of the meteorite body.

    Analysis of cosmogenic radionuclides in Martian meteorites is a great radioanalytical challenge because of the high scientific value of these meteorites, and necessity to apply non-destructive methods of analysis, e.g., low-level gamma-ray spectrometry. The measured Mn, Na, and Al levels in two...

    A simple analytical method was developed for the determination of cosmogenic 22Na radionuclide in fresh water samples by ultra low-background g-ray spectrometry after radiochemical separation. The method consists in pre-concentration of 22Na(Na) by a ion exchange resin column from a large volume...

    In laboratory gamma spectrometric analyses, the procedures for estimating background usually overestimate it. If an empty container similar to that used to hold samples is measured, it does not consider the background attenuation by sample matrix. If a “blank” sample is measured, the...

    UniSampo and Shaman are well-established analytical tools for gamma-ray spectrum analysis and the subsequent radionuclide identification. These tools are normally run locally on a Unix or Linux workstation in interactive mode. However, it is also possible to run them in batch/non-interactive...

    Peak search and analysis of the programs often associate peaks found in gamma-ray spectra of the radionuclides that are not present in the sample. Such radionuclides have to be excluded from the reported results. The dilemmas connected with reporting of the results near the detection limit are...
