The distributions of U, Th, Io and Ra contents as a function of depth in 5.0-meter core samples from three stations in the Azov Sea were investigated in the summer of 1959. The absolute contents of U, Th, Io and Ra in sediments of the Azov Sea are approximately the same as those in littoral ocean deposits. The average uranium concentration in sediments of the Azov Sea was 1.3 x 10/sup -6/ grams per gram of sludge, while the uranium in the upper layers of the Black Sea sediments was 5.7 x 10/sup -6/ g/g. The average concentration of thorium is greater in deposits of the Azov Black Sea than it is in deposits of the Azov Sea. Apparently, the main part of the ionium precipitates from solution after being formed from the uranium in solution. The concentration of Ra was found to be 7.2 x 10/sup -13/ g/g of sludge in the Azov Sea. The Ra is continuously carried down by sediments which act as carriers. Hence, the amount of Ra is almost twice the equilibrium amount based on the amount of U present in solution. The ratio of Th to U is variable, but is always greater than three. (TTT)
