THE NATIONAL ACADEMIES
Advisers to the Nation on S~ienre' Engineering' and Medirine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of
distinguished scholars engaged in scientific and engineering research, cledicated to the
furtherance of science and technology and to their use for the general welfare. Upon the
authority of the charter grantee! 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.
Bruce M. Alberts is president of the National Academy of Sciences.
The National Academy of Engineering was established in ~ 964, under the charter of the
National Academy of Sciences, as a parallel organization of outstanding engineers. It is
autonomous in its administration ant! 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 ant! research, and recognizes the superior
achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of
Eng~neenng.
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 fecleral government and, upon its own initiative, to identify issues of
medical care, research, ant! 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 broact 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 Acaclemy, 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. Bruce M. Alberts and Dr. Wm. A.
Wulf are chair and vice chair, respectively, of the National Research Council

Preface
This study began with the observation by members of the Board on Radioactive
Waste Management (BROOM) that low-activity radioactive wastes in the United States
are managed uncler a patchwork of regulations that have evolved over the past 60 years-
since the beginning of large-scale production of nuclear materials under the Manhattan
Project. Today a broad spectrum of low-activity wastes originates from nuclear power
utilities; the use of radioisotopes in industry, medicine, and research; recovery of mineral
resources (mining, oil ant! gas production); and Department of Energy (DOE) sites.
Because statutes ant! regulations that control Tow-activity waste are based on the
origin of these wastes, rather than their radiological properties, regulation may be overly
restrictive in some cases, leacling to excessive costs ant! other burdens on the waste
generator. In other cases, some wastes may present greater potential risks to the public
than are generally recognized. The BROOM therefore believed that a National Research
Council study of current low-activity waste management and regulation, and an
assessment of options for improving the current system would be valuable for state and
federal policy makers, waste generators and regulators, and concerned members of the
public.
This interim report concludes the first half of the study by providing an overview
of Tow-activity waste characteristics, inventories, management and disposal practices, and
the federal and state authorities that control these wastes. The committee has attempted
to organize a great deal of diverse information into a succinct presentation and set of
findings that will provide a sound basis for the final report, which will describe and
assess options for improvements.
The committee would like to recognize the five sponsors that provided financial
support at the beginning of this study:
Army Corps of Engineers
Department of Energy
Environmental Protection Agency
Nuclear Regulatory Commission
Southeast Compact Commission.
Informative site visits were arranged by Rudy Guercia, DOE Richiand
Operations Office, Hanford, Washington site; Mike Ault, U.S. Ecology, also at the
Hanford site; Ken Alkema, Envirocare, Clive, Utah; and Louis Dell'Orco, Army Corps of

Engineers, FUSRAP sites near St. Louis, Missouri. The committee also thanks the
individuals who made presentations at our public meetings (see Appendix A).
The work of this committee was ably assisted by members of the BROOM staff.
John Wiley, stucly director, assistec! and acivisec3 the committee from its inception through
review of this interim report. DarIa Thompson, senior research assistant, provided the
extensive documentation ant! other data resources user! by the committee. Angela Taylor
and Toni GreenTeaf provided prompt and efficient assistance with logistical and financial
matters.
Finally, I want to thank the members of the committee for their dedication and
diligence. ~ especially appreciate the leadership skills and technical insights provided by
Michael Ryan, vice-chairman. Although of diverse backgrounds and expertise, the
committee respected the overall goal of this initial phase of the study, and each macle
significant contributions. I look forward to working with the committee and staff in
completing this study and the final report.
