Abstract
This study evaluates the radiological risk associated with the consumption of infant powdered milk in Albania. Infant powdered milk is the basic foodstuff for their growth and development in many countries around the world. The activity concentration of radionuclides (40K, 226Ra, 232Th and 137Cs) was measured in fourteen types by using the gamma-ray technique. The results indicated that the activity concentration of 40K, 226Ra and 232Th were detected in all selected samples, whereas 137Cs were not detected in most of them. The activity concentration of 40K, 226Ra and 232Th varies from 92.83 ± 4.32 to 400.53 ± 17.00 Bq kg−1, 0.80 ± 0.15 to 4.91 ± 0.28 Bq kg−1 and 0.19 ± 0.02 to 1.89 ± 0.14 Bq kg−1, respectively. The highest value for 137Cs was found to be 0.36 ± 0.03 Bq kg−1. The average values of Annual Effective Dose (AED) due to consumption of powdered milk were found to be 664.54 ± 31.11 μSv y−1 for infants ≤1 year and 138.53 ± 5.40 μSv y−1 for infants 1–2 years. The values of dose in this study were lower than the recommended limit of 1 mSv y−1 set by WHO/FAO and ICRP for all ages. Therefore, brands of powdered milk are safe, so, these can be normally consumed by infants in Albania.
