Background : Food consumption is one of the most important routes for radionuclide intake for the public ; therefore , there is the need to have a comprehensive understanding of the amount of radioactivity in food products . Consumption of radionuclide-contaminated food could in- crease potential health risks associated with exposure to radiation such as cancers . The present study aims to determine radioactivity levels in some food products (milk , rice , sugar, and wheat flour) consumed in Mali and to evaluate the radiological effect on the public health from these radionuclides . Materials and Methods : The health impact due to ingestion of radionuclides from these foods was evaluated by the determination of activity concentration of radionuclides 238U, 232Th, 40K , and 137 Cs using gamma spectrometry system with high-purity germanium detector and radiological hazards index in 16 samples collected in some markets , mall , and shops of Bamako-Mali . JRPR Results and Discussion : The average activity concentrations were 9 . 8 ± 0 . 6 Bq/kg for 238U, 8.7± 0 . 5 Bq/kg for 232Th , 162 . 9 ± 7 . 9 Bq/kg for 40K , and 0 . 0035 ± 0 . 0005 Bq/kg for 137Cs . The mean values of radiological hazard parameters such as annual committed effective dose , internal haz- ard index , and risk assessment from this work were within the dose criteria limits given by in- ternational organizations (International Commission on Radiological Protection and United Nations Scientific Committee on the Effects of Atomic Radiation) and national standards . Conclusion : The results show low public exposure to radioactivity and associated radiological impact on public health . Nevertheless , this study stipulates vital data for future research and regulatory authorities in Mali .
