摘要：
The idea behind this study was to investigate the most popular magnesium dietary supplements as a potential additional source of 210Pb in the human diet. The paper presents the results of 210Pb activities determined in different magnesium supplements, as well as an estimation of the annual effective radiation doses from 210Pb decay. The results showed that the highest value of 210Pb activity was found in a magnesium supplement of natural origin ( dolomite) with a value of 2.97 +/- 0.18 mBq g(-1). The highest annual radiation dose from 210Pb obtained from the magnesium daily recommended value ( 0.4 g of pure Mg) was calculated for dolomite tablets as 3.71 +/- 0.02 mu Sv center dot year(-1).
