dc.description.abstractFood consumption is one of the main entry routes of radionuclides into the human body. Concentrations of radionuclides of natural origin vary according to several factors such as local geology, climate and agricultural practices. High background radiation areas have attracted much interest from a radiation protection point of view. The Poços de Caldas Plateau is located in south-eastern Brazil and is regarded as a high background radiation area. The situation of the resident population in the region of Poços de Caldas is of special interest for public health surveillance. The activity concentrations of radionuclides of natural origin in 19 groups of food and drinking water were determined. These radionuclides were quantified using gamma spectrometry, ultra low level alpha and beta total counting, and alpha spectrometry, after group preparation and/or radiochemical separations. The results of this study showed that the food groups analysed give rise to a low effective ingestion dose. Calculations were performed using the total radionuclide concentration in each food group, the mass consumed per day by each population group, the total time considered, and the dose intake of each radionuclide. The average annual effective dose received by members of the urban population on the Poços de Caldas plateau was 0.555 mSv.pt_BR
