VI PREFACE AND ACKNOWLEDGMENTS Jones of USNRDL, who prepared the autoradiographsof the tissues. In addition, Dr. W. P. Norris of Argonne National Laboratory made autographs of specific tissues. Dr. Rachael Reed of USNRDL performed the microscopic pathological studies of the tissues from the animals in whom radioisotopes were deposited internally. Lt. Col. R. J. Veenstra, VC, U. S. Army, was in charge of the care of all the experimental animals collected in the field and returned to the United States Naval Radiological Defense Laboratory. Dr. E. R. Thompkins made the facilities of the chemical technology division of the USNRDL available and provided technical advice on the radiochemical aspects of the project. The continuous help and cooperation of the Trust Territory representatives in particular, Mr. Maynard Neass, District Administrator of Majuro Atoll and their aid in obtaining the necessary control data on Marshallese inhabitants was indispensable to the success of this study. Particular help was obtained from Mr. John Tobin, the district anthropologist, whose knowledge of the Marshallese language and habits, in addition to services as an interpreter, were invaluable. The initial measurements on skin and clothing contamination were made by Lt. J. S. Thompson, MC, USN, of V. P. 29 Squadron. Weare indebted to him for furnishing his records on the contaminated individuals and the initial decontamination that was performed by his group. The care and the study of these human beings would not have been successful unless “the Marshallese had accepted the importance of their being under careful medical observation and of gathering medical data. At all times these people were most plersant, cooperative and actively participated in the project. In particular the project officer wishes to express thanks to the Magistrates of the groups, to the Marshallese health aids, school teachers, and nurses. It is quite impossiblf to acknowledge the assistance of the numerdus individuals in various agencies who assistafl in collection of data and editing of the variofs chapters. The Project Officer wishes to cofmmendall of the professional and technical members of the group for their excellent motWWation, initiative, and voluntary long hours offextra work that were essential for the accomphishmentof the clinical and research objectives ad the rapidcollection of the preliminary dath in the field. It is quite evident that the ehtire study of the exposed individuals was @ cooperative endeavor involving numerousacti¥ities, and that it would have been impossible eq¥cept for the splendid spirit of unselfish coopeyftion by all concerned. The fine team work of fhe group itself made it possible for realistic faily reports on all of the above phases to be forwarded daily to responsible agencies andfthus keep authorities informed of the course Rnd severity of events following this untowardjand unavoidable accident. Upon completion of t ie initial phase of the study, primary respons ility for writing reports on the variouse p ases was delegated as follows: C. A. Sondhe is, dosimetry; N. R. Shulman, clinical coursd and care; R. A. Conard, skin lesions: V. P.[Bond, hematology; 5. H. Cohn, internal depogiti The final publication pf this nenograph on humanradiation injury Fepresents the completion of the finest in coopfration and team work of a diverse group whp willingly sacrificed personal ambitions and] desires for the good of the project at large.
