RESUMO

This paper presents results of 137Cs concentration measured from a guava tree cultivated after the first decontamination work of one of the sites where the worst Brazilian radiological accident occurred. The present work aims to verify how the 137Cs is transported and distributed along the tropical trees. Bi-dimensional analyses of the radial distribution of 137Cs in the main trunk are also presented. Neither symmetrical nor homogeneous behaviors of the specific activity distribution in the tree rings were observed.
