An earnest, often chilling account of the experiments with chemical and biological agents as well as radiation. Undue Risk strongly supports [Moreno's] contention that the rights of human subjects deserve to be held paramount over any needs of national security. -- Daniel J. Kevels, The New York Times Book Review
A thoughtful look into the unfortunate penchant of 20th-century governments to test deadly weapons on their own citizens. -- Kirkus Reviews
Between 1949 and 1969, the U.S. Army conducted over 200 field tests as part of its biological warfare research program, releasing infectious bacterial agents in cities across the U.S. without informing residents of the exposed areas, Moreno reveals in this chilling, meticulously documented casebook. -- Publisher's Weekly
Although each chapter deals with a different set of experiments, the author weaves these studies together into a seamless account that is well-organized and fascinating to read. One appealing facet of the book is the many interesting tangents it takes. Moreno's book is an effective means to stir debate on the ethical issues involved in experimentation involving human subjects. -- The Left Atrium
