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 discrete gamma radiation in the interaction of 14.9-MeV neutrons and a natural copper sample is investigated with the total gamma radiation measurement technique. One hundred seven prompt gamma rays, which come mainly from the reactions (n,n'), (n,2n), (n,np), (n,d), (n,p) and (n,) of 63Cu and 65Cu, are identified by a high-resolution gamma-ray analysis code. According to the systematic knowledge of 14.9-MeV neutron-induced 63,65Cu(n,x) reactions, nine final nuclei are identified, and 139 possible transitions are designated. The differential elemental production cross sections of 107 gamma lines at 90 deg and 79 gamma lines at 55 deg are determined. The nine integral isotopic cross sections of 11 reaction channels including 63Cu(n,n')63Cu, 63Cu(n,2n)62Cu, 63Cu[(n,np) + (n,d)]62Ni, 63Cu(n,p)63Ni, 63Cu(n,)60Co, 65Cu(n,n')65Cu, 65Cu(n,2n)64Cu, 65Cu[(n,np) + (n,d)]64Ni, and 65Cu(n,p)65Ni are also obtained. The present results are in good agreement with some recent experimental and evaluated results.
