| 目的 掌握浙江省舟山地区居民常食海产品中3H和14C的放射性水平,为评估食用海产品所致辐射健康风险提供数据支撑。方法 2024年3—10月,在浙江省舟山的嵊泗和普陀地区码头以采购方式采集海鱼、海虾、海蟹、海贝和海藻等5类居民日常食用海产品共计14份,分别测定各海产品中组织自由水氚(TFWT)、有机结合氚(OBT)和14C放射性活度浓度。结果 部分海产品中TFWT和OBT放射性活度浓度低于最小可探测活度(MDA),活度浓度范围分别为< MDA~1.37 Bq/kg(鲜重)和< MDA~0.79 Bq/kg (鲜重),均低于《食品中放射性物质限制浓度标准》(GB 14882-1994)指导值。14C放射性活度浓度范围为2.90~82.77 Bq/kg(鲜重)。结论 舟山地区5类海产品中3H和14C放射性水平较低,均远低于国内外标准限值,处于本底水平。 |

| Objective To determine the 3H and 14C radioactivity levels in seafood commonly consumed by residents in the Zhoushan area, Zhejiang province, and to provide data for assessing the radiation-induced health risks caused by seafood consumption. Methods From March to October in 2024, a total of 14 samples encompassing five categories of daily-consumed seafood (i.e., fish, shrimp, crab, shellfish, and seaweed) were purchased from docks in the Shengsi and Putuo areas, Zhejiang province. The radioactivity concentrations of tissue-free water tritium (TFWT), organically bound tritium (OBT), and 14C in the seafood were determined. Results The TFWT and OBT radioactivity concentrations in some seafood were lower than their minimum detectable activity (MDA), ranging from < MDA to 1.37 Bq/kg (fresh weight) and from < MDA to 0.79 Bq/kg (fresh weight), respectively. Both were lower than the concentration limits specified in Limited concentrations of radioactive materials in foods (GB 14882-1994). The 14C radioactivity concentrations were also determined, ranging from 2.90 to 82.77 Bq/kg (fresh weight). Conclusions In the Zhoushan area, the 3H and 14C radioactivity levels are far lower than the limits stipulated in the related standard, representing the background levels. |
