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.”

The formation of a plasma potential is experimentally investigated in a fully-ionized collisionless plasma flow along converging magnetic-field lines in the presence of a single ECR point. When the ECR occurs in the region of converging region, the potential profile is observed to be drastically modified. The resultant potential structure consists of a negative potential dip and a subsequent positive potential hump working as a plasma-flow dike potential, which persists in the steady state when the ECR point is located in a region of good curvature of the magnetic configuration. However, this potential structure temporally collapses when the ECR point is located in a bad curvature region. The phenomenon is considered to be caused by low-frequency flute and drift instabilities.
