The main concern about radium as a phosphate has
been its intense radioactivity (226Ra) as a component of
phosphate-rock minerals. Little or no description of
these phosphate compounds can be found in the scientific
literature. Yet, the chemistry of Ra should closely
resemble that of the corresponding barium salts. Therefore,
the following descriptions are those which will
form the desired radium phosphate compound, even
though these salts have apparently not been prepared
heretofore nor have their physical and chemical properties
been described.
