[4. 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. FE. 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 ?seaass, District Administrator of Majuro Atoll and their aid in obtaining the necessary control data on Marshallese inhabttants was indispensable to the success of this study. Particular help was obtained from Mr. John Tobin, the district anthropologist, whose knowledge of the Marshallese Janguage and habits, in addition to services as an interpreter, were invaluable. The initial measurements on skin and clothing contamination were made by [a. J. 8. Thompson, MC. USN. of V. P. 29 Squadron. We are 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 in ouite impunnible to acknowlaige the wemtance of the numerous individuals in vari- ous agencies who assisted in collect on of «lata and eliting of the various chapters The Pro- ject Officer wishes to commend all of the profemional and technical members of the group for their excellent motivation, initiative, and voluntary long hours of extra work that were eswential for the accomplishment of the clinical and research objectives and the rapid collection of the preliminary data in the tield. It 1s quite evident that the entire study of the ex- posed individuals was a cooperative endeavor involving numerousactivities, and that it would have been impossible except for the splendid 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 responsible agencies and thus keep authorities informed of the course and severity of events following this untoward and unavoidable acecident. Upon completion of the initial phase of the study, primary responsibility for writing re- ports on the variouse plinses was delegated as follows: C. A. Sondhaus, dosimetry: N. R. Shulman, clinical Course and care: Ro A. Con- ard, skin lesions: Vo?) Bond, hematology: S. H. Cohn, internal de position. The tinal publication of this monograph on human radiation injury represents ‘the completien of the finest in cooperation and team work of a diverse group who willingly sacrificed personal ambitions and desires for the good of the project at large. It was a distinct privilege to be chosen to direct the medical team, areal pleasure to edit and integrate the separnte reports and finally realize their fruition as a homogeneous monograph. FE. PP.
