NOTICE: The project that is the subject of this report was approved by the Governing Board of the National Research Council, whose members are drawn from the councils of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The members of the committee responsible for the report were chosen for their special competences and with regard for appropriate balance.
This report has been reviewed by a group other than the authors according to procedures approved by a Report Review Committee consisting of members of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine.
The Institute of Medicine was chartered in 1970 by the National Academy of Sciences to enlist distinguished members of the appropriate professions in the examination of policy matters pertaining to the health of the public. In this, the Institute acts under both the Academy’s 1863 congressional charter responsibility to be an adviser to the federal government and its own initiative in identifying issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine.

Preface
In May 1995, the Office of the Surgeon General (OTSG) of the U.S. Army contacted the Institute of Medicine, requesting that it consider studying the health and ethical implications of conducting military operations in low-level nuclear environments. The request was prompted by the Surgeon General's participation with the North Atlantic Treaty Organization (NATO) in the development and standardization of procedures and equipment for detection, measurement, removal, and disposal of low-level radioactivity.
The IOM responded in July 1995 with a proposal to establish an expert committee to undertake the study, which was funded in September 1996. The committee's charge was developed in conjunction with the OTSG and consisted of two major tasks. In the first, we were to review draft NATO radiation protection guidance from a technical perspective and suggest improvements. The Army was most interested in receiving that review as quickly as possible. This report fulfills that desire. Our second task will be to consider broader issues of law and ethics.
We have included sufficient technical background in this first report that it can stand alone. Nevertheless, the reader should recognize that without the law and ethics component, the committee's work is incomplete. The second report, due a year from now, will expand the current report to consider the ethical, moral, and legal basis from which soldiers are exposed to and protected from radiation. The development of a complete system of radiation safety for the soldier will require not just the technical information discussed in this report but also the ethical foundations to be presented in the next.
Making this report useful to the widest possible audience within the Army has been a challenge. The technical basis of radiation safety is complex and given to its own jargon. On the one hand, we have made every effort to be as precise as possible in the discussion of background material. On the other hand, we have made some difficult choices to leave out some details that, if included, would have compromised clarity. We hope that diverse groups from radiation safety specialists to combat soldiers will find this report useful.

Acknowledgments
The committee and staff are grateful to LTC Carl A. Curling (Medical Nuclear, Biological, and Chemical Staff Officer) at the Office of the Army Surgeon General. As our project officer, he worked to explore the scope of the overall project, organized briefings and materials for the committee, and acted as a liaison to other military staff. We also acknowledge the important work of LTC John Bliss (International Chairman, NATO Working Group 2 on Low-Level Radiation) and LTC William J. Klenke, LTC Curling's predecessor, in initiating and supporting this project. COL David Jarrett (Director, Military Medical Operations Office, Armed Forces Radiobiology Research Institute), CPT Marc Umeno (Nuclear Medical Science Officer, US Army Nuclear and Chemical Agency), MAJ Debra Schnelle (Manager, Medical Health Physics Program; US Army Center for Health Promotion and Preventive Medicine), MAJ Brett Armstrong (Chief, Nuclear, Biological, and Chemical Sciences Branch; US Army Medical Department Center and School), CAPT Richard LaFontaine (US Navy), and LCDR Phillip Liotta (US Marine Corps) presented useful background material and perspective to the committee. Others whose efforts enhanced this report are Institute of Medicine-National Research Council staff—Claudia Carl, Mike Edington, and Linda Kilroy; and consulting editors—Peter Slavin and Beth Gyorgy.
