Abstract
In HPGe gamma spectrometric analysis of 210Pb in aerosol filter samples, the activity concentrations were corrected for self-attenuation and sample heights. Corrections were evaluated using the Monte Carlo simulation toolkit Geant4 and the Gespecor software. Calculations were made for 46.5 keV gamma line of 210Pb in Petryanoff (FPP) and fiberglass aerosol filters of varying heights. The IAEA RGU-1 reference material of different heights in a similar beaker served as a standard source. As a result, the approximations were found to calculate corrected efficiencies for samples with different heights. The method was applied for the study of 210Pb content in air in Estonia.
