In this survey the concentrations of the radioactive nuclides uranium ²³⁴U and ²³⁸U 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. As results showed, ²³⁴U and ²³⁸U concentrations in natural origin calcium and magnesium supplements were significantly higher than in other, synthetic ones. The highest ²³⁴U and ²³⁸U activity concentrations were determined in tablets from mussel’s shells. The radiochemical hazard was assessed and the highest annual radiation dose was found in ²³⁴U and ²³⁸U present in supplements produced from shells or dolomite rock.

在这项调查中，确定了波兰成人中最流行的钙和镁补充剂中放射性核素铀²³⁴ U和²³⁸ U的浓度。还研究了这些补充剂是否包含铀同位素，并且可能是人类饮食中的潜在来源，并且对消费者的有效辐射剂量价值产生影响。分析过的钙和镁药物包含有机或无机化合物，其中几种天然来源是贻贝的壳，鱼提取物或沉积岩。结果表明，天然来源的钙和镁补充剂中的²³⁴ U和²³⁸ U浓度显着高于其他人工合成的钙和镁。最高²³⁴从贻贝壳中测定片剂中的U和²³⁸ U活性浓度。对放射性化学危害进行了评估，发现由贝壳或白云石岩石制成的补品中存在的²³⁴ U和²³⁸ U最高年度辐射剂量。
