VI PREFACE AND ACKNOWLEDGMENTS Jones of USNRDL, who prepared the autora- diographsof 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 thefield and returned to the United States Naval Radiological Defense Laboratory. Dr. E. R. Thompkins made the facilities of the chemical technology division of the USNRDLavailable and pro- vided 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 pleasant, 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 impossible to acknowledge the assistance of the numerous individuals in vartous agencies whoassisted in collection of data and editing of the various chapters. The Project Officer wishes to commendall of the professional and technical members of the grour for their excellent motivation, initiative, and voluntary long hours of extra work that were essential for the accomplishment of the clinica! and research objectives and the rapidcollectior of the preliminary data in the field. It is quite evident that the entire study of the ex. posed individuals was a cooperative endeavo1 involving numerousactivities, and that it woulc have been impossible except for the splendic spirit of unselfish cooperation by all concerned The fine team work of the group itself made it possible for realistic daily reports on all of the above phases to be forwarded daily to re sponsible ugencies and thus keep authoritie: informed of the course and severity of event: following this untoward and unavoidable acci dent. Upon completion of the initial phase of th study, primary responsibility for writing re ports on the variouse phases was delegated a: follows: C. A. Sondhaus, dosimetry; N. R Shulman, clinical course and care: R.A. Con ard, skin lesions: V. P. Bond, hematology: 5 H.. Cohn, internal deposition. The final publication of this monographor human radiation injury represents the comple tion of the finest in cooperation and team worl of a diverse group who willingly sacrificec personal ambitions and desires for the gooc of the project at large. It was a distinet privi lege to be chosen to direct the medical team a real pleasure to edit and integrate the sepa rate reports and finally realize their fruition as a homogeneous monograph. FE. P.
