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⁻¹ for ²¹⁰Po, ²³⁸U, ²³²Th and ⁴⁰K respectively, whereas they are below the detection limit for ¹³⁷Cs and ²²⁶Ra. The annual effective dose due to intake of ²¹⁰Po, ²³⁸U, ²³²Th and ⁴⁰K ranged from 280 and 800 μSv y⁻¹ 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.
