[en] Uranium content in dicalcium phosphate (DCP), prepared from the Syrian phosphoric acid (SPA) and the products utilizing it directly in yeast and alcohol factories, has been followed. It has been found experimentally and by calculations that the amount of uranium transferred from the SPA to both DCP and baker's yeast was negligible and of no practical significance for the materials that may be added to, such as poultry diets, flour, paste and others. It may be concluded from these results that uranium would not be the primary obstacle for using the crude SPA (or uranium-free) or its products as a direct alternative.
