- Abstract
This article reports that knowledge of radionuclide or trace element retention and translocation to plants following an aerial contamination event, is necessary for the evaluation of human exposure through consumption of contaminated vegetables. Radionuclides released as fallout can be deposited either on the ground or on the leaves of plants. Thus, terrestrial plants can be contaminated by radionuclides through two pathways, namely root uptake and surface deposition. Before absorption and translocation into plants, radionuclides need to be previously retained by contaminated organ surfaces. Retention of aerial contaminants depends on four groups of factors, specifically, factors related to the chemical and physical characteristics of the radionuclide concerned, factors related to the mechanism aerial contamination.
