The U.S. Department of Energy Isotope Program is pleased to announce lead-203 (Pb-203) has been added to our catalog and is available for purchase. Pb-203 has drawn interest as a SPECT imaging isotope analogue to the therapeutic Pb-212, an alpha-emitter. Its addition to the NIDC Catalog establishes a theranostic matched pair of isotopes. Pb-203 will be shipped on a monthly basis with the first…
