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.”

A series of basic transport physics experiments are performed in Columbia Linear Machine, which generates a steady-state collisionless cylindrical plasma column in uniform axial magnetic field. The focus is on the isotopic scaling of ion thermal conductivity due to ion temperature gradient-driven modes. The experiments are performed using two different gases: Hydrogen and Deuterium. The results indicate reduction of thermal transport with increasing isotopic mass leading to a scaling K[perpindicular] ~ Ai-0.5, where Ai is the mass number of the isotope of hydrogen. This inverse gyro-Bohm scaling is similar to the tokamak results, but is in stark contradiction to most present theoretical models predicting Bohm (Ai0) or gyro-Bohm (Ai0.5) scaling. A series of experiments to explore the physics basis of this scaling has been also performed.
