Abstract |
|
|
| Food is any substance that provides nutritional support to the human body and the biological safety of the food is always taken into account, however contamination with radionuclides is also possible. The objectives of this study were to evaluate the activity concentrations of natural radionuclides (238U, 226Th, and 40K) of some selected imported canned foods commonly consumed in Abuja, Nigeria, and their radiological health hazard using sodium iodide detector. The results obtained showed a mean activity value of 2.43±0.02Bqkg-1, 0.38±0.02Bqkg-1, and 69.74±2.43 Bqkg-1 for 238U, 226Th, and 40K respectively. The results also showed that the mean value of radium equivalent activity was 9.17 Bqkg-1, while the values of internal hazard index, absorbed dose rate (DR) and annual effective dose equivalent (AEDE) were 0.03, 4.78 nGyh-1, and 23.45μ Svy-1 respectively. The mean values of the Annual Gonadal Effective Dose (AGED) and that of the representative gamma index were 34.37 µSvy-1and 0.07 respectively. The overall values obtained were below the world-permissible values of the United Nations Scientific Committee on the Effect of Atomic Radiation (UNSCEAR). It can be concluded that the canned foods analyzed in this study do not have any significant radiological concerns. |
