Wright officially sworn in for third term at the NRC
The Nuclear Regulatory Commission recently announced that David Wright, after being nominated by President Trump and confirmed by the Senate, was ceremonially sworn in as NRC chair on September 8.
This swearing in comes more than a month after Wright began his third term on the commission; he began leading as chair July 31. His term will conclude on June 30, 2030.

Being a high-Z material, mercuric iodide (HgI2) has a relatively high gamma-ray absorption coefficient. Its low charge carrier mobilities, however, have somewhat hampered the interest in using this material as a room-temperature gamma-ray spectrometer. By using the Frisch collar technology, the influence of the low charge carrier can be significantly reduced. The growth of HgI2 by the Faile method in a horizontal furnace fortuitously produces tetragonal prismatic crystals. These crystals with appropriate dimensions can be fabricated into Frisch collar spectrometers. With the Frisch collar technology, 1.8% energy resolution for 662-keV gamma rays has been achieved.
