Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.”

It is shown that basic measurements made from well-defined source detector configurations can be readily converted into benchmark quality results by which Monte Carlo N-Particle (MCNP) input stacks can be validated. Specifically, a recent measurement made in support of national security at the Nevada Test Site is described with sufficient detail to be submitted to the American Nuclear Society's Joint Benchmark Committee for consideration as a radiation measurement benchmark. From this very basic measurement, MCNP input stacks are generated and validated both in predicted signal amplitude and spectral shape. Not modeled at this time are those perturbations from the more recent pulse-height-light tally feature, although what spectral deviations are seen can be partially attributed to not including this small correction. The value of this work is as a proof-of-concept demonstration that well-documented historical testing can be converted into formal radiation measurement benchmarks. This provides evidentiary support that validated virtual testing could eventually be carried out for various detection system technologies including algorithms, new detector designs, constructions, and arbitrary source and shielding assemblies.
