Francis Cucinotta (Health Physics and Diagnostic Sciences) accepted an invitation to speak during the National Academy of Sciences’ Gilbert W. Beebe Symposium on the Future of Low-Dose Radiation Research in the United States. His talk focused on systems radiation biology, which addressed the government’s potential responsibilities in this area. He cited as examples the implications of 80 million computerized tomography scans completed in the United States each year, the reactor accidents in Fukushima, Japan, and Chernobyl, Russia, the necessary $120 billion clean-up project in Hanford, Washington, and the ongoing debate about nuclear waste storage at Yucca Mountain, Nevada.
