Zbigniew Jaworowski (17 October 1927 – 12 November 2011)[1][2] was a Polish physician, radiologist and alpinist. He chaired the United Nations Scientific Committee on the Effects of Atomic Radiation in 1981 and 1982. He was an investigator for projects by the U.S. Environmental Protection Agency and the International Atomic Energy Agency. Later in his career, Jaworowski disputed that ionizing radiation from the Chernobyl disaster was a major catastrophe for human health and wrote that the movement to remove lead from gasoline was based on a "stupid and fraudulent myth". Outside of his expertise in radiology, Jaworowski published articles criticizing mainstream climate science, including in magazines published by Lyndon LaRouche.
