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 present status of research on the ZT-40M Reversed-Field Pinch (RFP) will be described. RFP discharges have been sustained for times (27 ms) >> the classical resistive diffusion time, implying the existence of a flux-sustainment mechanism (“dynamo”). This mechanism opens the possibility for a steady-state RFP reactor utilizing a unique form of non-inductive current drive. Te > 500 eV has been obtained for 400 kA aischarges with ∼ 4 × 1019 m−3. Total energy confinement time τE has reached 0.7 ms with a Lawson parameter of 5 × 1016 m−3 s for discharges with = 8×1019 m−3 and Te = 330 eV at a plasma current of 330 kA and 0.33 T total confining field at the wall. Reactor-like βθ ∼ 10–20% is routinely obtained for plasma currents from 60–400 kA (β ∼ βθ/2). Scaling of τE ∼ I(2.2±0.4) is found, more than adequate for a compact RFP reactor.
