THE NATIONAL ACADEMIES
Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council.

Preface
The Committee on Assessment of Security Technologies for Transportation was appointed by the National Research Council (NRC) in response to a request from the Transportation Security Administration (TSA) for a study of technologies to protect the nation’s air transportation system from terrorist attacks. The committee judged that the best way to provide a timely response would be to produce a series of short reports on promising technologies, focusing on specific topics of greatest interest to the sponsor. This is the second of four such topical reports, all of which focus on air transportation security.1 The committee believes that the air transportation environment provides a test case for the deployment of security technologies that could subsequently be used to protect other transportation modes as well.
The discovery in February 2004 of the biological poison ricin in a Senate office building in Washington, D.C., highlights the fact that the terrorist’s arsenal now includes not only the all-too-familiar weapons such as small arms and explosives, but also chemical and biological agents. This expanding arsenal demands that policy makers and transportation authorities consider the deployment of new defensive technologies to respond to the new threats. In this report, the committee explores defensive strategies that could be used to protect air transportation spaces (specifically, airport terminals and aircraft) against attack with chemical or biological agents and makes recommendations with respect to the role of TSA in implementing these strategies.
The committee acknowledges the speakers from government and industry who took the time to share their ideas and experiences in briefings at the committee’s meetings. The committee would like to offer special thanks to Jiri Janata and Richard Rowe, who were the major contributors to the writing of this report. The following former committee members also greatly assisted the work of the current committee through their participation in many of its activities: Thomas S. Hartwick, chair through May 31, 2005; Len Limmer, consultant; and Elizabeth H. Slate, Medical University of South Carolina. Finally, the committee acknowledges the contributions to the completion of this report from National Materials Advisory Board director Gary Fischman, consultant Greg Eyring, and NRC staff members James Killian and Teri Thorowgood.
