Isotope production and applications


Isotopes produced at IPF are critical for medical diagnosis and disease treatment. These positron emission tomography images were made possible using isotopes produced at LANL.

The LANL Isotope Program utilizes unique capabilities to produce radioisotopes that are in short supply. The Isotope Production Facility (IPF), a 100 MeV proton bombardment station located at the Los Alamos Neutron Science Center (LANSCE), is a premier facility able to conduct high current irradiations for large scale production, as well as delicate, low current experimental work. The Program also maintains a robust hot cell facility for isotope processing, as well as a glovebox line within the LANL plutonium facility.

The LANL Isotope Program is part of the DOE Isotope Program, sponsored by the U.S. Department of Energy, Office of Science, Office of Isotope R&D and Production.

LANL-produced isotopes for medical, industrial & research applications

  • Strontium-82 (82Sr), used for cardiac imaging
  • Germanium-68 (68Ge), used for diagnostic procedures
  • Actinium-225 (225Ac), used for targeted alpha therapy (TAT)
  • Sodium-22 (22Na), used as a source for positron emission tomography
  • Arsenic-73 (73As), used for environmental research
  • Additional isotopes can be produced on demand

We have partnered with the TRIUMF facility to receive irradiated targets that are processed for aluminum-26 (26Al) and silicon-32 (32Si).

Increasing availability of new isotope products

The LANL Isotope Program is also engaged in the development of new isotopes for application in the fields of medicine, fundamental nuclear physics, national security, environmental science and industrial applications. Los Alamos National Laboratory possesses a unique combination of facilities and staff expertise that enable the production, purification and distribution of a variety of isotopes and associated applications.
