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 University of Rochester Laboratory for Laser Energetics Laser Direct-Drive 100-Gbar Campaign requires fuel capsules with specified limits on the number of localized surface defects in the 0.1- to 1-µm range. Schafer Livermore Laboratory has applied techniques of bright-field conventional imaging and charge-coupled-device–based dark-field microscopy as a possible method of characterizing the number and sizes of local particle-like defects on these capsules. Through simple experiments, we are able to correlate measured localized light-scattering levels with sizes of spherical polystyrene test particles. We have developed an engineering concept for whole-surface capsule scans based on quantitative dark-field microscopy as well as conventional imaging microscopy. This system and technique will be particularly useful during capsule development and capsule handling (transport, assembly, etc.) investigations.
