The radioactive determination of uranium in sea water

The determination of small amounts of uranium of the order of parts per hundred million has usually been carried out by indirect radioactive measurements. Such measurements cannot be employed except when the radio-elements are known to be in equilibrium. The separation of the uranium and its isotopes in such small amounts, is accomplished with the use of an ion-exchanger and separated in a radioactively pure state with the use of co-precipitators, the iron (and aluminum) being added. The alpha-particle activity of the uranium is determined as a measure of its concentration. The method is tested by two control tests. A, variance of 3.0% for these tests substantiates the validity
of the method but the efficiency of the extraction was approximately 50%. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
