Seeking Antimony-119 Test Batch Evaluators
.
The U.S. Department of Energy Isotope Program (DOE IP) is developing the capability of producing tellurium-119m (Te-119m) as well as its daughter isotope antimony-119 (Sb-119). The DOE IP is currently seeking researchers to evaluate Sb-119 samples from a recent test batch (and future batches). This material will be provided free of charge (except shipping fees) in exchange for technical and other relevant feedback that will help the DOE IP validate the production process and set appropriate future specifications.
To express your interest in becoming a qualified test batch recipient of Sb-119, please click the link below and fill out the required information by Friday, January 17th. An NIDC representative will promptly follow up with you directly with more information.
Antimony-119 (t1/2 = 38.9 h) is an Auger emitter 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). Its parent isotope tellurium-119m (t1/2 = 4.7 d) is produced at the Isotope Production Facility located at Los Alamos National Laboratory 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. At this time, only Sb-119 will be provided directly for evaluation. Since the material will be provided free of charge, any publications that arise from research using this material must acknowledge the DOE IP as the isotope provider.
