Karen Silkwood

Karen Gay Silkwood (February 19, 1946 – November 13, 1974) was an American laboratory technician and labor union activist known for reporting concerns about corporate practices related to health and safety in a nuclear facility. She worked at the Kerr-McGee Cimarron Fuel Fabrication Site in Crescent, Oklahoma, making plutonium pellets. She was the first woman ever elected to the union's negotiating team at Kerr-McGee. After testifying to the Atomic Energy Commission about her safety concerns, she was found to have plutonium contamination in her body and her home.
