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.

A sample counting cell for monitoring ultralow-level 85Kr in environmental air samples has been designed. The cell consists of ∼10 g of hydrogen mor-denite covered with 0.075-mm aluminum foil. The 85Kr is adsorbed by the hydrogen mordenite inside the counting cell. The radioactivity of 85Kr in the cell is measured by a modified external gas flow proportional counter. A refined separation method for the purification of 85Kr in the air sample has also been developed. The low detection limit for this improved counting system, including the refined separation procedure, is ∼0.02 pCi/cm3 based on 50-ℓ air samples at 1 atm. This counting method is also compared in detail with other methods.
