Measurement of the Radioactivity Levels for Some Food Products Imported to Iraq and Estimation of the Risk to Consumers

2021 Indian Journal of Forensic Medicine & Toxicology  
In this study, Uranium ( 238 U), Thorium ( 232 Th), Radium ( 226 Ra) and Potassium ( 40 K) activity concentrations were measured in 34 samples of biscuit, pastry, dessert, cakes and nestles manufactured in Turkey, Kingdom of Saudi Arabia, Emirates, in addition to locally produced biscuit sample manufactured in Iraq using gamma-ray spectrometry system. The average activity concentrations were 69.09±24.89 Bq/kg for 238 U, 26.75±11.13 Bq/kg for 232 Th, 4.86±1.16 Bq/kg for 226 Ra and 178.84±58.39

The effective doses arising from ingestion of naturally occurring radioactive materials in the investigated food samples ranged from 0.068±0.02 mSv/y for adults (age > 17 y) to 0.191±0.05 mSv/y for children (age 1-2 y), with a mean value of 0.12 mSv/y. It was found that the estimated potential radiation doses for investigated population groups were below the dose constraint of 0.3 mSv/y. The corresponding average radiation risk for all population groups (6×10 -6 per year) was found to be significantly lower than that considered acceptable in the relevant International Atomic Energy Agency (IAEA) safety standards (10 -5 per year). The results presented in current study confirm that the potential radiation doses and radiological hazards associated with intake of the natural radionuclides in the imported and locally produced food species is acceptable and well within permissible limits. Hence, the imported and locally produced food species investigated in this study were considered safe for human consumption with respect to radiological hazards.
