Abstract
In the present work, different brands of baby formula and cereal consumed in Jordan were analyzed for their radioactivity content. The activity concentrations of 40K varied with the designated age group in formula with the average concentrations being (in Bq/kg): 160.2 ± 33.5, 219.0 ± 35.0 and 265.2 ± 56.3 for the age groups of 0-6 months, 6-12 months and 1-3 years, respectively. 226Ra was not detected in any of the samples, while 232Th was detected in nearly half the samples with concentrations ranging from 0.22 to 0.82 Bq/kg. 137Cs was detected in only two samples with concentrations of 0.94 and 3.15 Bq/kg. The concentrations of 40K and 232Th in cereal were in the ranges of 23-294 and 0.49-1.48 Bq/kg, respectively. The resulting committed dose was assessed and found in the range of 154-613 μSv, with insignificant contribution from 137Cs, which is within the worldwide range but generally higher than the worldwide average of 290 μSv.
