A system of ~99mTc production Based on distributed Electron accelerators and Thermal separation

摘要

A system has been developed for the production of ~99mTc based on distributed electron accelerators and ther- mal separation. The radioactive decay parent of ~99mTc, ~99Mo, is produced form ~100Mo by a photoneutron reac- tion. Two alternative thermal separation processes have been developed to extract ~99mTc. Experiments have been performed to verify the technical feasibility of the pro- duction and assess the efficiency of the extraction pro- cesses. A system based on this technology enables the economical supply of ~99mTc for a large nuclear phar- macy. Twenty such production centers distributed near major metropolitan areas could produce the entire U.S. supply of ~99mTc at a cost less than the current subsidized price.
