Researchers Improve Production for Short-Lived Scandium Radioisotopes
Scandium radioisotopes are potentially useful for cancer therapy and medical imaging such as positron emission tomography (PET) scans, but the difficulty of producing sufficient amounts and purities of these isotopes limits their use. New research describes ways to make and irradiate accelerator targets for scandium to increase production and purity. The process recycles the calcium target material with more than 95% efficiency.
Tunable Bonds: A Step Towards Targeted At-211 Cancer Therapy
The astatine isotope astatine-211 (At-211) shows promise as a cancer therapy, but scientists know little about how it interacts with chemicals. Researchers have now discovered a new tunable bonding interaction between At-211 and a class of chemicals known as ketones. This discovery has the potential to improve cancer therapy drugs by linking At-211 to cancer targeting molecules.
New Imaging Isotope Meets Promising Therapy Isotopes
Researchers have demonstrated the production, purification, and potential application of cerium-134. The isotope decays into lanthanum-134, which is useful for positron emission tomography (PET) imaging. The results mean that cerium-134 could support medical treatments based on actinium-225 or thorium-227.
Department of Energy Announces $4 Million for Isotope R&D
Today, the U.S. Department of Energy (DOE) announced $4 million in funding for 10 awards across 5 efforts to advance R&D for isotope production. This funding is part of a key federal program that produces critical isotopes otherwise unavailable or in short supply for U.S. science, medicine, and industry.
Department of Energy to Provide $2 Million for Studies to Accelerate the Evaluation of Novel, Medically Relevant Isotopes for Use in Pre-clinical and Clinical Medical Trials
The U.S. Department of Energy (DOE) announced up to $2 million in new funding to support translational research and development (R&D) of novel, medically relevant isotopes to accelerate evaluation for usage in pre-clinical and clinical trials.
Department of Energy to Provide $2 Million for Traineeship in Isotope R&D and Production
Today, the U.S. Department of Energy (DOE) announced up to $2 million to establish a traineeship program to advance workforce development in the field of isotope production, processing, and associated research, with preference to minority serving institutions.
Suzanne E. Lapi: Then and Now / 2011 Early Career Award Winner
University of Alabama Birmingham professor Suzanne Lapi founded and heads a research group focused on the radiochemistry and development of production techniques of isotopes for medical imaging and therapy.
Scientists Recruit New Atomic Heavyweights in Targeted Fight Against Cancer
Researchers from Berkeley Lab and Los Alamos National Laboratory have developed new methods for the large-scale production, purification, and use of the radioisotope cerium-134, which could serve as a PET imaging radiotracer for a highly targeted cancer treatment known as alpha-particle therapy.
ORNL-produced plutonium-238 to help power Perseverance on Mars
Mars 2020 will be the first NASA mission that uses ORNL-produced plutonium-238, the first U.S.-produced Pu-238 in three decades. ORNL’s Pu-238 will help power Perseverance across the Red Planet’s surface.
