| Abstract |
A tentative reference method for the measurement of total radium and radium-226 in environmental water sources is described. Samples are collected, preserved with acid-barium carrier treatment, and analyzed for total radium and/or radium-226. For samples analyzed for total radium, the radium is separated from the sample with barium and lead carriers. The barium and radium are then separated from the lead carrier, precipitated as the sulfate, filtered, and counted for alpha activity. For samples analyzed for radium-226, the radium is separated from the sample with barium carrier, dissolved and transferred to a de-emanation bubbler, the radon-222 daughter allowed to grow in, the ingrown radon-222 de-emanated from the solution and transferred to a scintillation counting cell, and alpha counted. Recoveries are determined from the added and found (recovered) barium carrier. Counting efficiencies are determined with prepared standard reference samples. Results are reported in pCi/liter. |
