摘要: 采用同位素示踪法对常见的17种水生物中210Po含量进行了测定,还分析了虾不同部位中210Po含量。水生物可食部分中 210Po含量范围为0.15~34.8 Bq/kg(鲜),不同水生物可食部分中210Po含量差别较大。甲壳类、头足类和贝类水生物对210Po有很强的浓集能力,尤其是牡蛎、八爪鱼、螃蟹和鱿鱼中210Po含量很高,分别为34.8、25.0、20.3和17.2 Bq/kg(鲜),超过了我国现行国标食品中放射性物质限制浓度中的限值。虾不同部位中210Po含量呈现规律分布,头部中210Po含量最高,壳次之,肉最低。

Abstract: Concentrations of 210Po in 17 kinds of aquatic organisms were determined by an isotope tracing method, and 210Po concentrations in different parts of shrimps’ bodies were also measured. The concentrations of 210Po in edible parts of aquatic organisms were 0.15-34.8 Bq/kg of fresh weight, and the variations between different aquatic organisms were large. Aquatic organisms of crustaceans, cephalopods, and shellfishes have strong enrichment capability for 210Po, and especially the 210Po concentrations in oysters, octopus, crab,squid were 34.8, 25.0, 20.3, and 17.2 Bq/kg of fresh weight respectively, which are higher than our national limit for the 210Po concentration in food. 210Po concentrations in different parts of shrimp’s bodies presented a distribution pattern: the highest in heads, moderate in shells, and the lowest in meats.

Key words: 209Po, tracer, 210Po concentration, aquatic organisms, shrimps
