Abstract

This study investigates the 210Pb activity concentrations in tobacco and cigarettes available in Slovakia, utilizing two specific extraction methods including the Sr Resin sorbent used in extraction chromatography, and the AnaLig Sr01 sorbent, which operates based on molecular recognition principles. The findings revealed significant variations in 210Pb activity concentrations, with concentrations ranging from 13.3 to 33.8mBq/g in tobacco, and from 16.8 to 28.5mBq/g in cigarettes. The average 210Pb activity per cigarette was 14.4mBq ± 1.7mBq. Annual effective doses for smokers were calculated, with values for tobacco ranging from 27.9 to 126.7 µSv and for cigarettes from 25.5 to 115.7 µSv. The study highlights the importance of comparing these two methods to ensure an accurate assessment of 210Pb exposure and evaluation of radiological risks associated with smoking in Slovakia.
