AbstractAbstract
[en] This is a report on the Transport Pathways of Thorium, Uranium, Rare Earths Elements, Radium-228 and Radium-226 from Soil to Farm Animals. The investigation is taking place in the State of Minas Gerais, Brazil, where an ore body (Morro de Ferro) exists that contains about 30,000 metric tons of thorium and more than 50,000 metric tons of rare earth elements. The ore body, which is believed to be about 60 million years old, has eroded to the surface and has been inundated by ground water. Nearby farmers are cooperating in the study. The analytical procedures have been modified to adapt them to the large volumes of biological material. The soils from the farm plots have been sampled, analyzed and characterized by standard pedological methods. Analyses for most of the substances of interest have been completed in pilot samples of vegetables and cow bone
