It was found that the concentration of thorium in the waters of the Azov Sea varied within wide limits from 4 x 10/sup -9/ g/l for the open, wide part of the sea to 219 x 10/sup -9/ g/l at the point where the river Don empties into the Azov Sea. The concentration of thorium in the water depends on the amount of suspended matier, and on the climatic conditions and place of sample selection. The water near the shore contains more susperded matter, and hence, is higher in thorium. The ratio of RdTh/Th was found to be 1.43 by extracting the thorium in a composite sample with tributylphosphate from nitric acid solution, and separating polonium from thorium on an anion exchanger. The RdTh content in this sample was determined by an emanation method from the growing in of ThX. The Th content was also determined on the composite sample. UX/sub 1/ was used to correct for yield.
