Karl Z. Morgan was a physicist at the Manhattan Project & Oak Ridge National Laboratory, where he was director of health physics from the late 1940s until his retirement in 1972. He collaborated with leading trial lawyer Ken M. Peterson to write this extraordinary memoir about the dawn of the nuclear age & the moral dilemmas associated with nuclear energy. A deeply humane & religious scientist, Morgan regards his own role in meeting the challenges presented by the "angry genie" of nuclear energy with the same unblinking eye he focuses on government, the military, & the nuclear industry. He tells harrowing tales of radiation accidents & near-disasters, & shows the actual & potential consequences of the clumsiness, recklessness, & carelessness of fallible human beings. After his retirement from Oak Ridge, Morgan served as a key expert in the two most significant radiation cases of the century, Silkwood v. Kerr-McGee Corporation (1979) & Allen v.

United States (1984). Morgan's testimony capped a career of conscientious service to, & criticism of, the military industrial complex-a career that won him many awards, including twenty years as chair of the Internal Dose Committee of the International Commission on Radiological Protection, which sets radiation standards in all countries.
