| Abstract: | 211Pb and its daughters are produced in a generator system which utilizes the distillation of the intermediate daughter219Rn from223Ra. The radium is precipitated as the stearate to isolate the parent while allowing the gaseous daughter to emanate. While the yield of the system is low, approximately 10%, the radionuclidic purity is extremely high. No measurable223Ra is found in the product.223Ra is separated from its parent,227Ac, by cation exchange.Deceased.Research supported in part by the Office of Health and Environmental Research, U.S. Dept. of Energy. |
