Accumulation of 137Cs and 40K in aboveground organs of tropical woody fruit plants

Abstract

Distribution of 40K and 137Cs in tissues of the Citrus aurantifolia was measured by gamma spectrometry. A simple theoretical model is also proposed to describe the temporal evolution of 40K activity concentration in such tropical woody fruit species. This model exhibits close agreement with the 40K experimental results, in the leaf growing and fruit ripening processes of lemon trees.
