Oral Histories

Gary Petersen is the former vice president of federal programs for TRIDEC, the Tri-City Development Council, which works to promote economic growth for Washington State’s Tri-Cities (Pasco, Kennewick, and Richland) area. Before TRIDEC, he worked at the Hanford site for Battelle, serving as news manager, and in the International Nuclear Safety Program at Pacific Northwest National Laboratory. In this interview, Petersen discusses the studies Hanford conducted in biology and health physics, the continuing cleanup of the Hanford site, and the future of radioactive waste disposal. Additionally, he discusses his involvement in producing the book Nuclear Legacy: Students of Two Atomic Cities, that looked at the connections between Richland, WA and Slavutych, Ukraine through the perspectives of American and Ukrainian students.

Roger Cloutier was born in North Attleborough, Massachusetts in 1930. After serving in the U.S. Navy during the Korean War, he pursued a career in health physics. In 1959, he moved to Oak Ridge to work for ORINS, the Oak Ridge Institute of Nuclear Studies (now Oak Ridge Associated Universities, or ORAU), and went on to serve as director of ORAU’s Professional Training Programs. In this interview, Cloutier recalls his career at ORAU and describes the medical innovations he was a part of, including advances in the use of radioisotopes to treat disease. He gives a history of other programs at ORAU, and explains how ORINS was started at the suggestion of Manhattan Project physicist Katharine Way.

Jay Shelton is an American physicist and science and math teacher. In this interview, he recalls his experiences from nearly three decades as a high school teacher in Northern New Mexico. He provides an overview of how radiation works and how alpha, beta, and gamma rays differ. Shelton explains the health risks associated with radiation and stresses the importance of quantitative analyses of risks from certain radiation sources. He argues that the general public often overplays many of these risks. He also goes over changes in public perception towards radiation. For example, he points out that radiation was believed to have health benefits prior to the 1930s. Throughout the interview, Shelton describes how a variety of scientific instruments work, including Geiger counters and oscilloscopes, and expounds on the importance of a hands-on approach in science education. He also discusses his personal collection of scientific artifacts, including Revigators and other nuclear-related objects.

Dunell Cohn was born in Oak Ridge in 1944. Cohn’s father, Waldo, was recruited to work on the Manhattan Project in Chicago in 1942 for his work on radioisotopes at Berkeley and Harvard during the 1930s. Shortly thereafter, he was transferred to Oak Ridge, where he developed a method to separate the fission products from the nuclear reactor. He also pioneered the radioisotope program at Oak Ridge, producing radioisotopes in large quantities that could then be used for medical and biological research. Dunell recalls what it was like growing up as a child at Oak Ridge and describes his father’s effort to desegregate the town by integrating the public school system. He also remembers his father’s love for music and his role in creating Oak Ridge’s symphony orchestra.
