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 K-40 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. Ra-226 was not detected in any of the samples, while Th-232 was detected in nearly half the samples with concentrations ranging from 0.22 to 0.82 Bq/kg. Cs-137 was detected in only two samples with concentrations of 0.94 and 3.15 Bq/kg. The concentrations of K-40 and Th-232 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 mu Sv, with insignificant contribution from Cs-137, which is within the worldwide range but generally higher than the worldwide average of 290 mu Sv.
