Since the main source of ingestion exposure to natural radioactivity originating mainly from foodstuffs, the current study aims to assess the total committed doses from 226Ra, 232Th and 40K from some food products. Thirty food samples such as wheat, beans, meat, chicken, fish, Molokai, coffee, tea and powder milk were randomly collected from some markets in Cairo and dried using an electric oven. Specific activity for the 226Ra, 232Th and 40K concentrations in food samples was measured using a high-purity germanium spectrometer. The effective dose from the resulting food was calculated using the dose conversion factors recommended by the United Nations Scientific Committee on the Effects of Atomic Radiation, 2000. The specific activity for the selected food samples varies from 3.5±0.1 to 8.8±0.2, 1.0± 0.1 to 4.6±2.2 and 20±1.0 to 718±2.0 Bq.kg-1 for 226Ra, 232Th and 40K respectively. The obtained annual ingestion dose was lower than dose constrain and lower than the public dose which gave indication for radiation food safety.
