A method was developed for concentrating thorium in large volumes of natural water (200 to 500 l) using iron hydroxide precipitation at low temperature. The contents of thorium and ionium in the Black Sea are (2.2 plus or minus 0.2) x 10/sup -9/ and (2.5 plus or minus 1.0) x 10/sup -13/ g/l, respectively. The content of thorium decreases from the coastal area to the open sea. Moreover, the thorium content decreases much faster than the ionium because Iarger quanities of Th/sup 232/ are found in coarse terrigeneous suspension, while ionium occurs in fine colloidal suspensions that do not settle as easily to the bottom and are carried farther into the open basin.
