Application of mathematical calibrations in measurements of gamma emitting radionuclides in honey samples and borosilicate filters

Mathematical efficiency calibrations for the specific matrices such as honey and borosilicate filters are performed. Their reliability is experimentally tested. The influence of the choice of the matrix composition in the mathematical calibration on the results is investigated. After the verification of the mathematical models, the results for activity concentrations in the test samples are presented. •Mathematical efficiency calibrations for the specific matrices such as honey and borosilicate filters are done.•An effect of the choice of the matrix composition in the mathematical calibration on the results is investigated.•Mass activities of Cs-137 and K-40 in test samples of honey were determined.•Activity concentrations of Be-7 and Pb-210 in borosilicate filters are reported.
