Isotope Availability May 2021
The DOE Isotope Program is pleased to announce the availability of some of our most requested isotopes for purchase.
New Inventory of Silicon-32
The DOE Isotope Program recently replenished its inventory of silicon-32. Largely used for marine research, silicon-32 is valuable to understand and model the global climate.
Thorium-228 Now in Routine Production
Thorium-228 is available routinely and is ready for purchase. Its decay products radium-224 and lead-212 are used in cancer-fighting medical research on metastatic skin cancer and neuroendocrine tumors.
New monthly batches of high-specific activity copper-67 are planned and scheduled to ship to customers on May 19, June 16, and July 14, 2021. Deadlines to order from these batches are May 10, June 3, and July 1, 2021 respectively. The DOE IP has developed this production capability to increase the domestic supply of this isotope to the research community.
Barium-133 New Availability
Millicurie quantities of barium-133 are now available for purchase. Barium-133 is used for various purposes, including as an x-ray radiocontrast agent and as a gamma source in multiphase flow meters used in the oil and gas industry.
Americium-241 in Routine Production
Americium-241 is now in routine production and is available for purchase. Americium-241 is used in a variety of industrial applications including oil and gas exploration, smoke detectors, and moisture gauges.
Actinium-225 in Routine Production
Accelerator-produced actinium-225 is in routine production, and the DOE IP is working to ramp up production to meet increasing demand.
This alpha-emitting radionuclide and its decay product bismuth-213, from an actinium-225/bismuth-213 generator, have gained considerable interest within the medical community for their radioimmunotherapy applications. Limited quantities are available from the next batch, ready to ship to customers starting June 23. The deadline to order from this batch is June 1, 2021.
The High Flux Isotope Reactor at Oak Ridge National Lab is fully operating again and tungsten-188 is available for purchase now. Tungsten-188's decay product, rhenium-188, is a gamma and beta-emitting radionuclide of growing interest within the nuclear medicine community for a variety of therapeutic applications.
The DOE IP can produce a new batch of yttrium-86 on demand. Due to its positron-emitting properties, the isotope holds promise as a PET imaging agent and as a theranostic pair to yttrium-90 for cancer treatment.
Did you know the DOE IP has astatine-211 available on demand? The program is developing capabilities to produce this isotope across the United States. Produced and shipped through our University Isotope Network, astatine-211 is of interest to the medical community for its use in cancer treatment.
The DOE Isotope Program has Radium-224/Lead-212 generators available on demand. Produced at Oak Ridge National Laboratory, the generator can be used to produce both lead-212 and bismuth-212 for cancer research and therapy.
