The activity concentrations of (210)Po have been determined in a total of 24 representative diet samples from Seville (south of Spain), inferring from the obtained values the annual intakes of (210)Po by ingestion of the affected population and the corresponding committed effective doses. The annual intakes of (210)Po and, consequently, the corresponding doses of this radionuclide show a high variability in correspondence with the variability in the composition of the analysed samples over time, and their magnitude is comparable with the estimated ones in other regions/countries of the world with similar diet habits (countries where the marine products have a considerable weight in the diets). Committed effective doses by ingestion higher than 0.1 mSv y(-1) have been estimated exclusively for (210)Po, reflecting the importance of this radionuclide and this route of incorporation in the magnitude of the total doses received by the affected population from natural sources.
已测定了来自西班牙南部塞维利亚的总共24个具有代表性的饮食样本中（210）钋的活度浓度，并根据所得值推断受影响人群因摄入（210）钋的年摄入量以及相应的待积有效剂量。（210）钋的年摄入量以及因此该放射性核素的相应剂量，随着时间的推移，与所分析样本组成的变化相对应，呈现出高度变异性，其量级与世界上其他具有相似饮食习惯的地区/国家（海产品在饮食中占相当比重的国家）的估计值相当。仅针对（210）钋估计出摄入的待积有效剂量高于0.1 mSv y⁻¹，这反映了该放射性核素以及这种摄入途径在受影响人群从天然源接受的总剂量量级中的重要性。
