Web12 de mar. de 2015 · Another promising beta-emitting radiopharmaceutical—though not yet commercially available—is 47 Sc. Like the above-described radioisotope 67 Cu, 47 Sc is both a beta and gamma emitter, having a half-life of 3.35 days. With a maximum β − energy of 600 keV for bombarding tumors and with the medically-useful diagnostic gamma line … WebEstimated Yield Values for Radioisotopes Produced in the 86-in. Cyclotron at the ORNL Targets for radioisotope production are relatively small, typically ranging from a few milligrams to several grams, and the postirradiation radiochemical processing steps used are essentially laboratory scale. Thus, process wastes are usually low volume.
