dc.description.abstractActivity concentrations of the radionuclides 137Cs, 40K, 226Ra and 228Ra were determined in Brazil nuts acquired at points of sale between 2010 and 2013. Results indicated that the estimated annual effective radioactive dose due to ingestion of Brazil nuts is 27% of the annual dose limit of 1 mSv y-1 for public exposure, according to the Interna-tional Commission on Radiological Protection (ICRP). To estimate this dose the highest activity concentration ob-tained for each radionuclide was considered, assuming an annual consumption of 1.5 kg y-1 per individual.pt_BR
