In 1994, Jonathan Moreno became a senior staff member of a special commission created by President Clinton to investigate allegations of government-sponsored radiation research on unknowing citizens during the cold war. The top secret documents he helped to declassify revealed a shocking truth-- that human experimentation played an extensive role in this country"s attempts to build and protect against weapons of mass destruction. In Undue Risk, Moreno presents the first comprehensive history of the use of human subjects in atomic, biological, and chemical warfare experiments from World War II to the twenty-first century. From the courtrooms of Nuremberg to the battlefields of the Gulf War, Undue Risk explores a variety of government policies and specific cases, including plutonium injections into unwitting hospital patients, U.S. government attempts to recruit Nazi medical scientists, the subjection of soldiers to atomic blast fallout, secret LSD and mescaline studies, and the feeding of irradiated oatmeal to children. It is also the first book to go behind the scenes and reveal the government"s struggle with the ethics of human experimentation and the evolution of agonizing policy choices on unfamiliar moral terrain. As the threat of foreign and domestic terrorist attack continues to grow, the need for our country to defend itself against insidious weapons is greater than ever. Can a democracy justify using humans in potentially risky experiments in order to answer scientific questions vital to national security? Exploring the possibilities, Undue Risk highlights a program of human experimentation that is a moral model for all others, civilian and military.
