FOREWORD This final report thoroughly documents the technical and logistic accomplishments of the Enewetak Radiological Support Project. The reader will readily recognize the magnitude and significance of the effort. This document duly recognizes all aspects of the project except one, possibly the most important though not so obvious to the casual reader. This was truly a cohesive scientific "expedition" because of the achievements, both personal and collective, of all the participants from a variety of governmental and private agencies. Particularly impressive to visitors at Enewetak was the ability of this group of scientists, technicians and support personnel to work in an environmentrelatively hostile to the required sophisticated technology. Despite adverse conditions, this team collected samples of soil, performed radiochemical analyses on the samples, applied statistical analysis to the data, interpreted the results and provided guidance to the Joint Task Group virtually overnight so that the daily activities for removal of contaminated soil could continue. This concerted effort under the leadership of the Nevada Operations Office is remarkable;its absence would have severely hampered the accomplishments detailed in this report. William J.
