The Department of Energy’s University Isotope Network aims to facilitate more widespread shipment of short-lived isotopes. One such isotope, astatine-211, is showing promise at the University of Washington and Fred Hutchinson Cancer Center.
User Group Schedule
The DOE IP will host four virtual isotope user meetings focused on the following emerging alpha-emitters: actinium-225, astatine-211, lead-203/212, and new this year, cerium-134.

This can improve conversion of the radioisotope source’s beta decay emissions to electricity by using two converters instead of one. The result is greater power density for the power source.

New Approach to Radioisotope Power Sources for Improved Efficiency, Long Life

NextGen power sources may satisfy the need for long-term, compact power for use in remote or extreme environments.
