PR: American Nuclear Society welcomes Senate confirmation of Ted Garrish as the DOE’s nuclear energy secretary
Washington, D.C. — The American Nuclear Society (ANS) applauds the U.S. Senate's confirmation of Theodore “Ted” Garrish as Assistant Secretary for Nuclear Energy at the U.S. Department of Energy (DOE).
“On behalf of over 11,000 professionals in the fields of nuclear science and technology, the American Nuclear Society congratulates Mr. Garrish on being confirmed by the Senate to once again lead the DOE Office of Nuclear Energy,” said ANS President H.M. "Hash" Hashemian.

Resonance-neutron radiography is being developed at the National Bureau of Standards (NBS) for use in nondestructive evaluation (NDE) and assay (NDA) applications. To illustrate the method we determined the distribution and thickness of silver between two silver-brazed metal plates. The NBS electron Linac provided a pulsed source of epithermal neutrons. Neutron energy was determined using the time-of-flight technique. Neutrons were detected using a one-dimensional position-sensitive proportional counter containing 4 atm 3He, 6 atm argon, and 0.5 atm CO2 and having a spatial resolution of 5 mm. Transmission values, measured over the 5.2-eV resonance in 109Ag, were used to locate the silver. Simple area analysis of these values yielded the amount of silver that was present.
