Accumulation of sup 210 Po in foodstuffs cultivated in farms around the Brazilian mining and milling facilities on Pocos de Caldas plateau

Abstract

Several sample types from the environment of the uranium mining and milling facilities of Pocos de Caldas plateau (CIPC) in Minas Gerais state, Brazil have been assayed for their concentrations of uranium and its daughters. This paper presents the data for {sup 210}Po in food, soils and fertilizers in the CIPC region and, for comparison, the corresponding results from a vegetable garden in a control region in Joinville, in the state of Santa Catarina. The results show that vegetables from two gardens near the CIPC region have no significance differences in Po content, despite the closeness of one of the sites to a uranium mine. For some species of vegetables, however, nearsite values were twice those in the control region. Superphosphate fertilizers influence the accumulation of {sup 210}Po by plants, as well as the concentrations in soils, and their contribution is more evident than the local deposition. The major concentration in the leaf and stem suggests that the accumulation of {sup 210}Po in vegetables is due chiefly to its deposition on and absorption by their leaves. (author).
