Abstract

Investigation of radioactive traces in foods produced and exported mainly in Paraná State, Brazil, was carried out by gamma-ray spectrometry, a non-destructive nuclear method. The redistribution of 40 K concentration during the processing of soy ( Glycine max ) primary products (745±9 Bq kg −1 for soybean, 1473±15 Bq kg −1 for soy bran, and ⩽8.8 Bq kg −1 for commercial refined soy oil) was verified. The 40 K activity for all oil stages analyzed was lower than the limits of detection. Others foods such as sulfite-treated sugar, mate tea, and mint were analyzed. The activities for the natural nuclear chain ( 228 Th and 226 Ra) and the 137 Cs (artificial radionuclide) were presented.
