Abstract
The present invention provides a method for improving the recovery of cesium-131 (Cs-131) from barium (Ba) carbonate. Uses of the Cs-131 purified by the method include cancer research and treatment, such as for the use in brachytherapy. Cesium-131 is particularly useful in the treatment of faster growing tumors.
