Katy Huff on the impact of loosening radiation regulations
Katy Huff, former assistant secretary of nuclear energy at the Department of Energy, recently wrote an op-ed that was published in Scientific American.
In the piece, Huff, who is an ANS member and an associate professor in the Department of Nuclear, Plasma, and Radiological Engineering at the University of Illinois–Urbana-Champaign, argues that weakening Nuclear Regulatory Commission radiation regulations without new research-based evidence will fail to speed up nuclear energy development and could have negative consequences.
