DOWNLOAD EBOOK{Sup 99m}Tc, the daughter product of 99Mo, is the most commonly used radioisotope for nuclear medicine in the U.S. Experiments are being performed at Los Alamos National Laboratory and Argonne National Laboratory to demonstrate production of 99Mo using accelerators. The 1°°Mo([gamma], n)99Mo reaction in an enriched 1°°Mo target is currently under investigation. Three scaled low-power production experiments using a 20-MeV electron linac at Argonne have been performed to date. Two of these experiments used natural Mo targets and produced a total of 613 [mu]C of 99Mo. The third experiment used an enriched 1°°Mo target and produced 10.5 mCi of 99Mo. Following irradiation the targets were dissolved and the low specific activity solution was processed through an ARSII generator from NorthStar Medical Radioisotopes. Yields of {sup 99m}Tc>95% have been observed.
