Cancer-fighting treatment gets boost from Isotope Production Facility

Medical Isotope Work Moves Cancer Treatment Agent Forward - Los Alamos scientist Meiring Nortier holds a thorium foil test target for the proof-of-concept production experiments. Research indicates that it will be possible to match current annual, worldwide production of Ac-225 in just two to five days of operations using the accelerator at Los Alamos and analogous facilities at Brookhaven.
Isotope Production Facility produces cancer-fighting actinium
A new medical isotope project at LANL shows promise for rapidly producing major quantities of a new cancer-treatment agent, actinium 225 (Ac-225).
Using proton beams, the Lab and its partner Brookhaven National Laboratory could match current annual worldwide production of the isotope in just a few days, solving critical shortages of this therapeutic isotope that attacks cancer cells.
A collaboration between LANL, Brookhaven, and Oak Ridge national laboratories is developing a plan for full-scale production and stable supply of Ac-225.
Alpha particles are energetic enough to destroy cancer cells
Ac-225 emits alpha radiation. Alpha particles are energetic enough to destroy cancer cells but are unlikely to move beyond a tightly controlled target region and destroy healthy cells.
Alpha particles are stopped in their tracks by a layer of skin—or even an inch or two of air.
Economically viable supply of Ac-225 is lacking
One of the primary barriers to wider use of Ac-225 has been the lack of an economically viable supply.
Scientists at the Lab's Isotope Production Facility (IPF) recently completed a successful research and development project in which they explored the accelerator-based production of the isotope.
Producing medical imaging isotopes is a primary mission
Since 2005, a primary mission for IPF has been production of medical imaging isotopes such as strontium-82 for positron emission tomography, known as PET scans. In addition to medical imaging applications, IPF has had the mission of making isotopes available for
- national security,
- environmental studies and
- a variety of industrial and R&D applications.
The Ac-225 work is a first and important step toward the addition of a range of IPF-produced isotopes for medical therapy applications.
