First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

Magnetized Target Fusion (MTF) occupies an intermediate region between conventional Magnetic Fusion Energy (MFE) and Inertial Fusion Energy (IFE). A particular approach, extrapolated from the ongoing FRX-L experimental effort, involves the generation of a Field Reversed Configuration (FRC) suitable for translation along an axial magnetic field and cylindricalliner (i.e., converging flux conserver) implosion and pdV heating to burn conditions. The fusion gain, Q (ratio of DT fusion yield to the sum of initial liner kinetic energy plus plasma formation energy), sets the pulsed power-plant duty cycle. The modular power-plant embodiment recalls the Fast Liner Reactor (FLR) and shares stand-off and blast-mitigation features of the recent characterization of the Z-IFE. Recycle and economic remanufacture of destroyed front-end apparatus must be performed under tight cost constraints. A tin-lithium alloy is being investigated for multifunctional suitability as the liner, transmission-line, and primary coolant/breeder material. Key performance drivers are described.
