Are You Interested in Evaluating a Sample of Tellurium-119m?

The U.S. Department of Energy Isotope Program (DOE IP) is now capable of producing tellurium-119m (Te-119m) and is currently gauging interest for this isotope among the research community. Qualified test batch recipients are sought to evaluate material that will be provided free of charge and provide feedback to the DOE prior to routine production. Since the material will be provided free of charge, any publications that arise from research using this material must include the following acknowledgment:

"This research is supported by the U.S. Department of Energy Isotope Program, managed by the Office of Science for Nuclear Physics."
Tellurium-119m (T1/2 = 4.7 d) is the parent isotope to antimony-119 (Sb-119), an Auger emitter (T1/2 = 38.9 h), under investigation for use in targeted radionuclide therapy due to its ability to deliver a large radiation dose to a highly targeted region (micrometer- scale). Producing and distributing the longer-lived Te-119m extends the window for Sb-119 use in the field since it will continue to decay to Sb-119 over several days. A Te-119m/Sb-119 generator is under development by the DOE IP for customer use. 
The radioisotope is produced at the Isotope Production Facility located at Los Alamos National Laboratory (LANL) using a high energy proton beam to bombard an Sb metal target. The Te-119m is isolated at high specific activity from the Sb target in the on-site hot cell facility.
