PREFACE The publication of For the Record: A History of the Nuclear Test Personnel Review Program, 1978-1986 marks the conclusion of the most active period of the Nuclear Test Personnel Review (NTPR) program, established by the Defense Nuclear Agency (DNA) in 1978. The volume has two purposes: (1) to provide the public with useful information concerning personnel participation in U.S. atmospheric nuclear testing and the postwar U.S. occupation of Hiroshima and Nagasaki, and (2) to provide a public accounting of the NTPR effort, which has involved a series of actions on behalf of the nuclear test participants and veterans of the Hiroshima and Nagasaki occupation. The text is directed to a diversified readership, including veterans, Congress, the media, and other interested parties. For the Record attempts to serve the public by being relatively concise. This one volume synthesizes relevant information from a substantial number of published sources, including the 41-volume, 9,029-page history of atmospheric nuclear testing published earlier by the Defense Nuclear Agency. It also presents data elicited from unpublished sources, such as letters, memoranda, and speeches, and from interviews with NTPR personnel. Readers desiring additional information should consult the original sources, which are identified at the end of each chapter and in Appendices D through F. The body of this history divides into three basic parts. Chapters 1, 2, and 3 introduce the NTPR program and highlight organizational contributions. Chapters 4 through 6 concentrate on the nuclear operations, describing the detonations, personnel participation, and radiation safety measures. Chapters 7 and 8 focus on radiation dose, the former on radiation dose determination and the latter on medical studies of potential dose effects. Chapter 1, Introduction to the Defense Nuclear Agency and the NTPR © Program, contains the heart of the book. It identifies the origins, scope, and accomplishments of the program and then presents a summary table of radiation doses for veterans of the nuclear tests and the Hiroshima/Nagasaki occupation. iv
