This recommendation is consistent with other studies that have reviewed medical isotope supply in the United States and have come to the same conclusions (IOM 1995, Wagner et al. 1999, Reba et al. 2000).

RECOMMENDATION 2: Review enriched stable isotope inventory and evaluate domestic supply options if needed. The current inventory of enriched stable isotopes is decreasing and there is growing concern that the aging calutrons cannot be operated cost-effectively to meet demand if reopened. The DOE should evaluate the option of a domestic enriched isotope supply source to ensure availability for medical research.
