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

摘要

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