摘要

The purpose of this work was to evaluate the uptake of exogenous sup 226 Ra by carrot, brow-bean and cabbage. Greenhouse experiments were carried out with farm soils collected near the first Brazilian Uranium Mine and Mill and contaminated with sup 226 Ra solution. After the maturity, the plants were harvested, ashed and this nuclide was analysed by gamma spectrometry. Among the edible parts, sup 226 Ra content decreased in the following order: cabbage > brown-bean > carrot. Soil-to-plant transfer coefficients were of the order of 10 sup -2, values of 10 to 100 times greater than those observed in the region. The results emphasize the importance of irrigation water as a contamination pathway of human groups in the area.
