An inventive solution speeds up production of actinium-225

An Oak Ridge National Laboratory researcher has built a device that can speed up the separation of the medical radioisotope actinium-225 from irradiated thorium targets and withstand the high-radiation environment of a hot cell. In July, ORNL announced that Kevin Gaddis, a chemistry technician at the lab, had built and tested a prototype and was working to secure a patent for a device that cut separations time by 75 percent.
