Abstract
The uranium contents in phosphorites from North Africa, products of their processing (H3PO4, superphosphates, phosphogypsum), lignites from South Bulgaria and products of their burning, copper ores and concentrates have been determined by instrumental and radiochemical NAA. An evaluation of the contribution of the phosphoric fertilizers to the uranium content of soil, plants, breeding stock and man has been done.
