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.”

Macroscopic behavior of a high-beta and supersonic plasma flow is investigated in the HITOP device. It is found that a cylindrical plasma begins to rotate eccentrically around the center axis in a divergent magnetic mirror. The eccentric radius increases with the increase in the mirror ratio and the beta value of the plasma. The rotating frequency changes with the radial electric field in the plasma, which is controlled by end-plate biasing technique. The rotation direction and its velocity are consistent with E × B drift motion. This behavior seems to be a flute/ballooning mode driven by static and dynamic pressure gradient in a bad curvature region of the divergent field line.
