Popis: In this work, soil to plant transfer factor of 226 Ra and 228 Ra obtained in areas of traditional agricultural practices varied as a function of the considered cultivated species, but little variation was observed as a function of the soil type. Beans and soybeans presented a more important absorption than cereals (com, rice and wheat). Values of transfer factor of the legumes (beans and soybeans) were about an order of magnitude greater than the average obtained in areas of high natural radioactivity, while the results for the cereals did not presented such clear differences. Cultural inputs of 226 Ra and 228 Ra are occurring in agricultural areas, but few species can demonstrate it. Soil to plant transfer factor values for 226 Ra and 228 Ra, obtained in agricultural areas seem more applicable in models of risk evaluation.
