The Program also supports isotope production
and basic research at a suite of university accelerator and reactor facilities throughout the Nation to promote a reliable supply of domestic isotopes. Examples of isotope research required to meet national needs include positron-emitting radio nuclides to support the rapidly growing area of medical imaging using positron emission tomography (PET), isotopes supporting medical research used to diagnose and treat diseases spread through acts of bioterrorism, research isotopes for various scientific and biomedical applications, enriched stable isotopes, and alternative isotope supplies for national security applications and advanced power sources. One of the high priorities is to conduct R&D aimed at re-establishing a U.S. capability for enriched stable isotope production. Another high priority is a long-term research effort to produce Ac-225, an isotope that shows great promise in the treatment of diffuse cancers and infections if it can be produced in sufficient quantity and quality. Isotope Program research also provides training opportunities for workforce development in the areas of nuclear chemistry and radiochemistry. These disciplines are essential to the long-term health of the fields of radioisotope production and applications.
- Proposal
- Can we make Ac-225 using electron accelerators? Ac-225 half life is 10 days. Los Alamos can make world supply in a few days but a cheaper (desktop?) method is needed.
Science
- The Reaction
The half life of Ra-225 is 14 days and the half life of Ac-225 is 10 days.
