On uranium U and U radionuclides in calcium and magnesium supplements and the potential effective radiation dose assessment to the consumers.

In this survey the concentrations of the radioactive nuclides uranium U and U were determined in the most popular calcium and magnesium supplements for adults in Poland. It was also investigated whether the supplements contain uranium isotopes and could be a potential source in the human diet and have an influence on the value of effective radiation doses to the consumers. The analyzed calcium and magnesium pharmaceuticals contained organic or inorganic compounds, several of natural origin as mussel's shells, fish extracts, or sedimentary rocks.
