²¹⁰Po and ²¹⁰Pb activity concentrations in fish from the Slovenian part of Adriatic Sea, in the vicinity of a former uranium mine at Žirovski vrh and from the Slovenian market were determined. In addition, ²¹⁰Po and ²¹⁰Pb activity concentrations in squid from the Slovenian market and in mussels from the Slovenian part of the Adriatic Sea were also determined. Fish, squid and mussel consumption in Slovenia was assessed from the data available from Eurostat and Food and Agriculture Organisation (FAO) and the data used for the corresponding dose calculation. Fish species with the highest activity concentrations were grilled to assess possible loss of ²¹⁰Po during the food preparation process. Samples were freeze dried and radiochemical separation of ²¹⁰Po and ²¹⁰Pb was performed. Measurements of ²¹⁰Po were performed by alpha spectrometry and ²¹⁰Pb by a low background gas-flow proportional counter. ²¹⁰Po activity concentrations in fish, squid and mussels were from 0.039 to 35.0 Bqkg⁻¹ fresh weight and ²¹⁰Pb activity concentrations were from 0.08 to 3.03 Bqkg⁻¹ fresh weight. Grilling of fish resulted in no significant loss of ²¹⁰Po at 90°C. The assessed combined annual effective ingestion dose due to ²¹⁰Po and ²¹⁰Pb for fish, squid and mussels consumed in Slovenia is 47.6 μSv year⁻¹.
²¹⁰Po 和 ²¹⁰Pb 放射性活度浓度在亚得里亚海斯洛文尼亚部分的鱼类、Žirovski vrh 前铀矿区附近以及斯洛文尼亚市场的鱼类、鱿鱼和贻贝类中的 ²¹⁰Po 和 ²¹⁰Pb 放射性活度浓度进行了测定。从欧盟统计局和联合国粮食及农业组织（FAO）的数据评估了斯洛文尼亚的鱼类、鱿鱼和贻贝消费情况，并将这些数据用于相应的剂量计算。具有最高放射性活度浓度的鱼类采用烧烤方式，以评估在食品制备过程中 ²¹⁰Po 可能的损失。样品经冷冻干燥后，采用放射化学分离法对 ²¹⁰Po 和 ²¹⁰Pb 进行分离。²¹⁰Po 的测量采用α谱法，²¹⁰Pb 的测量采用低本底气流正比计数器。鱼、鱿鱼和贻贝中 ²¹⁰Po 的放射性活度浓度范围为 0.039 至 35.0 Bqkg⁻¹ 鲜重，²¹⁰Pb 的放射性活度浓度范围为 0.08 至 3.03 Bqkg⁻¹ 鲜重。在 90°C 下烧烤鱼类时，²¹⁰Po 无明显损失。由于在斯洛文尼亚消费的鱼类、鱿鱼和贻贝中的 ²¹⁰Po 和 ²¹⁰Pb，评估的年有效摄入量为 47.6 μSv year⁻¹。
