Seeking Antimony-119 Test Batch Evaluators

The U.S. Department of Energy Isotope Program 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 domestic researchers to evaluate Sb-119 samples from an upcoming test batch planed for Summer 2025.

Promethium Chemistry Breakthrough Could Unlock New Applications
