Charles Yulish has devoted his career to nuclear and environmental science. From an early age, Yulish fell in love with nuclear energy and set up a lab that received radioisotopes from the Atomic Energy Commission—who did not initially realize their samples were being sent to a high school student and his classroom lab. In this interview, Yulish remembers his teacher, who instilled in him a curiosity towards all things nuclear. He talks about his career in nuclear research—both public and private—throughout his 50 year career. He worked for many years for the United States Enrichment Corporation and its “Megatons to Megawatts” program. He also consulted with the Mescalero Apache Tribe in New Mexico, who wanted to set up a nuclear storage waste site on its land in the 1990s when the US government was considering such a program.
