This work presents first results of radioactivity measurements in selected early children's food (<year) which are commercially available, widespread, and typically consumed in Croatia. The samples are categorized according to growth of a child, from its first nourishment, adapted powdered milk, to its first solid food, cereal porridge powder, homogenized fruit porridge and finally mushed meals with vegetables and/or meat. Natural ⁴⁰K is detected and quantified in all of the samples (from 30 Bq/kg up to over 250 Bq/kg), with highest values in powdered milk (150–200 Bq/kg) and cereal porridge (maximum value 262 Bq/kg in the sample containing oats). ²²⁶Ra was visible in all types of foods in the majority of the samples in small amounts, not exceeding 0.92 Bq/kg. ¹³⁷Cs was detected only in some of the powdered milk samples with maximum measured activities (0.65 ± 0.32 Bq/kg and 0.38 ± 0.14 Bq/kg) found in the …
