In order to compare three different techniques and estimate radiological impact, activity concentration of 210Pb in coal, slag and ash samples from thermal power plant “Nikola Tesla”, Serbia, were measured, and results are presented in this study. Determination of 210Pb was carried out in three ways: using HPGe gamma spectrometer and via in-growth of 210Po and 210Bi by alpha-particle spectrometry and proportional counting, respectively. The results obtained for three different techniques were compared. Statistical analysis and comparison of methods were carried out by combination of Z score and χ 2 statistical tests. Tests results, as well as values of measured activities concentrations obtained by alpha and gamma spectrometry, showed that gamma spectrometry is a valid alternative to time-consuming alpha spectrometry for low level activity measurements of 210Pb. This remark is also valid even for gamma spectrometers with poor efficiency in low energy region.
