title: 210Pb in magnesium dietary supplements.
abstract: The idea behind this study was to investigate the most popular magnesium dietary supplements as a potential additional source of210Pb in the human diet. The paper presents the results of210Pb activities determined in different magnesium supplements, as well as an estimation of the annual effective radiation doses from210Pb decay. The results showed that the highest value of210Pb 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 from210Pb obtained from the magnesium daily recommended value (0.4 g of pure Mg) was calculated for dolomite tablets as 3.71 ± 0.02 µSv·year-1.
