FOREWORD
This report presents the final results of one of the projects participating in the military-effect
programs of Operation Redwing.

Overall information about this and the other military-effect

projects can be obtained from WT-1344, the “Summary Report of the Commander, Task Unit
3.” This technical summaryincludes: (1) tables listing each detonation with its yield, type,
environment, meteorological conditions, etc. ; (2) maps showing shot locations; (3) discussions
of results by programs; (4) summaries of objectives, procedures, results, etc., for all projects;

and (5) a listing of project reports for the military-effect programs.

PREFACE
Wherever possible, contributions made by others have been specifically referenced in the body
of this report and are not repeated here.

The purpose of this section is to express appreciation

for the many important contributions that could not be referenced.
Suggestions fundamental to the success of the project were made during the early planning
Stages by C.F. Miller, E.R. Tompkins, and L.B. Werner. During the first part of the operation,
L. B. Werner also organized and directed the analysis of samples at U.S. Naval Radiological
Defense Laboratory (NRDL). Sample analysis at NRDL during the latter part of the operation
was directed by P. E. Zigman, who designed and did much to set up the sample distribution center at Eniwetok Proving Ground (EPG) while he wasin the field.

C.M. Callahan was responsible

for a large share of the counting measurements at NRDL and also contributed to the chemical
analyses.
The coordination of shipboard construction requirements by J. D. Sartor during the preliminary phase, the assembly and checkoutof field-laboratory instrumentation by M. J. Nuckolls
and S. K. Ichiki, and the scientific staff services of E.H. Covey through the field phase were
invaluable. Important services were also rendered by F. Kirkpatrick, who followed the processing of all samples at NRDL and typed manyof the tables for the reports, V. Vandivert, who provided continuous staff assistance, and M. Wiener, who helped with the final assembly of this
report.

Various NRDL support organizations performed outstanding services for the project. Some
of the most notable of these were: the preparation of all report illustrations by members of the
Technical Information Division, the final design and construction of the majority of project instruments by personnel from the Engineering Division, the packing and transshipmentof all
project gear by representatives of the Logistics Support Division, and the handling of all radsafe procedures by members of the Health Physics Division. In this connection, the illustration
work of I. Hayashi, the photographic work of M. Brooks, and the rad-safe work of W. J. Neall
were particularly noteworthy.
The project is also indebted to the Planning Department (Design Division), and the Electronics
Shop (67) of the San Francisco Naval Shipyard, for the final design and construction of the ship
and barge platforms and instrument-control systems; and to U.S. Naval Mobile Construction
Battalion 5, Port Hueneme, California, for supplying a numberof field personnel.
The names of the persons who mannedthe field phase are listed below. Without the skills
