DETERMINATION OF RADIUM 226 IN MILL EFFLUENTS
Procedures are given for determination of Ra/sup 226/ in effluents from mills processing uranium ores. Alpha-energy spectra graphs are given for precipitates separated from the mill effluent by various methods. Samples for determination of Ra/sup 226/ were acidified with HNO/sub 3/ to make the sample 2% acid by volume, The radium is precipitated as sulfate with barium sulfate carrier and lead sulfate. These sulfates are dissolved in fuming perchloric acid, reprecipitated, and dissolved in EDTA-TEA solution. The pH of the solution is adjusted until barium and radium sulfates precipitate, leaving lead, radium daughters, and any thorium present in solution. The Ra/sup 226/ activity can be determimed by alpha counting at 3 hr and one week after precipitation. (M.C.G.)
