Assessment of the Annual Effective Dose due to Intake of Natural Radionuclides from some Food Samples

Abstract

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 226 Ra, 232 Th and 40 K 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 226 Ra, 232 Th and 40 K concentrations in food samples was measured using
