FOREWORD AND ACKNOWLEDGMENTS
The Lovelace Foundation for Medical Education and Research became involved in the de-
velopment of special-purpose slide rules in 1959 because of the need for an easy and convenient
method of evaluating the free-field effects of nuclear weapons. (Free-field is used here to de-
note weapons effects occurring near the surface of the earth in the absence of structures or of
unusual terrain features, such as hills, dales, and forests.) The first to recognize and give ex-
pression to this need was R. L. Corsbie, then Director, Civil Effects Test Operations, Division
of Biology and Medicine, United States Atomic Energy Commission (USAEC). A circular slide
rule was developed in 1959 and produced in 1960 (based on the 1957 edition of The Effects of
Nuclear Weapons) which was similar to the one reported here except that it was smaller and
permitted evaluation of fewer effects parameters. Soon after the production of this rule, plans
were made by the Defense Atomic Support Agency (DASA) and the USAEC to revise and update
The Effects of Nuclear Weapons. Concurrently, plans were made to update the slide rule; thus
the present computer was designed and produced to conform with the revised data appearing in
the effects manual. The new slide rule was designed to include pertinent material that had
not appeared on the previous one.
The interest and encouragement of Samuel Glasstone, editor of The Effects of Nuclear
Weapons, is gratefully acknowledged. Through his cooperation and the concurrence of DASA, it
was possible to obtain the needed effects data as they became available, many months before
the revised manual was published.
The authors wish to thank Chester W. Lytle and other personnel of the Lytle Corporation
for their assistance in constructing prototype slide rules and for their advice relative to
The finished drawings from which the slide rule was produced were prepared by Robert A.
Smith of the Department of Medical Illustration, Lovelace Foundation. From the same group,
Mrs. Joyce Blaine prepared the illustrative material and George Bevil handled the photographic
work for this report.
Kevin A. Doherty and Orville R. Pratt of the Physics Department assisted in the numeri-
cal treatment (both machine and manual) of effects data.
The manuscript was typed by Mrs. Maureen K. Gilmore, Mrs. Ruth P. Lloyd, and
Mrs. Isabell D. Benton.
Here’s what’s next.
