A set of measurements have been conducted to determine the activity-level of natural and artificial radionuclides in some baby foods commercialized in Italy. The measurements have been carried out using liquid scintillation, gamma, alpha and mass spectrometry. The activity concentrations ranged from 0.005 to 0.238, from 0.0082 to 1.65, from 0.0003 to 0.015 and from <13.6 to 233.3 Bq kg for Po, U, Th and K respectively, whereas they are below the detection limit for Cs and Ra. The annual effective dose due to intake of Po, U, Th and K ranged from 280 and 800 μSv y for infant 1 year old. These values lie well within the typical worldwide range of dose due to the ingestion of all natural radiation reported by UNSCEAR and they are below the internationally recommended level. This indicates that the baby food available in Italy would not pose any significant radiological impact to infant.
已进行了一组测量，以确定在意大利商业化的一些婴儿食品中的天然和人工放射性核素的活度水平。使用液体闪烁、伽马、阿尔法和质谱法进行了测量。活性浓度范围为 0.005 至 0.238，0.0082 至 1.65，0.0003 至 0.015 和 <13.6 至 233.3 Bq kg 分别为 Po、U、Th 和 K，而 Cs 和 Ra 的活度浓度低于检测限。婴儿摄入 Po、U、Th 和 K 的年有效剂量范围为 1 岁婴儿 280 至 800 μSv y。这些值位于 UNSCEAR 报告的所有天然辐射摄入所致剂量的典型全球范围内，并且低于国际推荐水平。这表明意大利提供的婴儿食品不会对婴儿造成任何重大的放射性影响。
