Abstract
The proposed method embodies a barium sulfate carrier precipitation, filtration through molecular filter membranes, and collection of activity after prescribed aging period. The method is sufficiently accurate and precise to indicate the potability of water and for use in general studies of radium in chemical hydrology. Amounts of radium as low as 0.1 μμc. can be detected by using 1 -hour counting times. Radium-226 is used as the standard and the results indicate about 100 to 110 % of the activity of the alpha-emitting radium isotopes as radium-223, radium-224, and radium-226.
