It is with great sadness that we learn of the death of Dr. Rudi Nussbaum, who died in Holland after a fall. Rudi was an avowed pacifist and Holocaust survivor and an expert on the health effects of radiation exposure. As his longtime friend, Lloyd Marbet writes: "His work as a Professor Emeritus of Physics and Environmental Science at Portland State University was instrumental in raising alarm over the health effects of radiation exposure. He wrote numerous papers on this subject and participated in gathering valuable information on workers and civilians that were exposed to radiation at Hanford and in surrounding communities, for which he became a vocal advocate for environmental justice. He helped bring the famous epidemiologist, Alice Stewart, to Portland, and promoted her life story. You can watch a short video interview with Rudi below.
