Ingestion doses and elemental composition of herbal plants and fish

It is known that the determination of ingestion doses of radioactive elements is a complex problem due to the different metabolic behaviours of the human beings. To contribute to this topic, this work presents the analysis of the ingestion doses of 40 K, 232 Th and 238 U in some species of herbal pl...

Description
Summary:It is known that the determination of ingestion doses of radioactive elements is a complex problem due to the different metabolic behaviours of the human beings. To contribute to this topic, this work presents the analysis of the ingestion doses of 40 K, 232 Th and 238 U in some species of herbal plants and fish. These analyses were done using technique of gamma ray spectrometry and applying the estimation models for ingestion dose of ICRP and IAEA. Furthermore, in this article was applied the analytic technique of Energy Dispersive X-ray fluorescence (EDXRF) in the analysis of elementary composition and concentrations of components in those same species of herbal plants and fish.
