nel arrived in the freld. Preliminary hematologic studies indicated that the udividuals probably had not received acutely fatal doses of radiation. The primary responsibilities: within the proj ect group were delegated as follows: Clinical observations and care LT ON. R. Shulman, MC, USN Organization and operation of laboratory Compilation and daily analysis of all data LT ROS. Farr, MC, USN Dr. V. P. Bond Decontamination and radiation measurement LT Gg) R. Sharp, MSC, USN Semor Petty Officer m charge of laboratory oP. K. Schork, HMC, USN As the ¢climeal preture developed, a further breakdown in responsibility was necessary. Coo mander R.A. Conard, MC, USN, and it Col G. &. Browning, MC, USA, were niade cesponsibbe for a danly survey of skin desions, and Or. 5. WH. Cohn was made responsible for studving the problems concerned with the exeretion of radioisotopes and the estiniites of body burdens tn the exposed individuals. The project offieer commends all of the professtonal and technical members of the group for their excellent motivation, mitiative, and voluntary long hours of extra work that were es sential for the accomplishment of the clinical and research objectives, and for the rapid eol- fection of the preliminary data in the field. It 1s emphasized that the work was a cooperative endeavor in which all were mutually dependent upon cach other. The willing efforts of all concerned constituted a remarkable example of team-work and sacrifice of personal ambitions and desires for the good of the project at large. The authors wish to express their gratitude and indebtedness to Dr. John C. Bugher, CAPT Van Tipton, and CDR Harry Etter, CAPT W. E. Kellum, MC, USN, and CAPT T. L. Willmon, Commanding and Executive Officers, respectively, NMRI; CAPT R. A. Hinners, USN, Director, NRDL, and CAPT A. R. Behnke, MC, USN, Associate Director, NRDL; all of whom gave unlimited support and reduced administrative procedures to a bare minimum, thus makingit possible for the unit to be assembled and underway in a matter of hours. On arrival at Kwajalein, RADM R. S. Clarke, USN, Commanding Officer, U.S. Naval Station, Kwajalein, supported Project 4.1 with all the facilities at his disposal. As a result, a laboratory and clinic was established and operating within 24 hours after arrival of the project personnel, . Project personnet also wish to acknowledge the outstanding contributions of Col C. S. Maupin, MC, USA, Field Command, AFSWP, CAPT H. H, Haight, MC, USN, Division of Milttary Application, AEC; Col K. Houghton, MC, USAF, Special Weapons Center, CAPT Donald Dement, MC, USN, CINCPAC Fleet; Drs. T. L. Shipman, T. White, and P. Harris of Los Alamos Scientific Laboratory; Dr. Gordon Dunning, Division of Biology and Medicine, AEC, and Dr. G. V. LeRoy, University of Chicago. During all phases of the early care of the exposed individuals, the foregoing participated as much as their other primary duties would permit. In addition the authors wish to thank them for the extensive and complete data which they collected in the atolls or their home laboratories and kindly furnished to the project personnel. The continuous help and cooperation of Trust Territory representatives and their aid in obtaining necessary control data on native Marshallese at Majuro is hereby acknowledged. The authors are particularly indebted to Mr. John Tobin. His help as an interpreter and his extensive knowledge of the Marshallese language and habits were invaluable. Licutentant J. 5. Thompson, MC, USN, furnished his records on the exposed individuals decontaminated by the radiation group of the VP-29 squadron stationed at Kwajalein. The authors wish especially to express their admiration for the excellent job done by the medical personnel of the U.S. Naval Dispensary, Kwajalein, in completing the extensive Liboratory examinations that were required to obtain a prompt initial evaluation of the severity of the radiation injury, The authors are deeply grateful to Dr. David A. Wood of the University of California Hos pital, San Francisco, and Dr. Edward L. Alpen and Miss Pat Roan of NRDL, for mvaluable aid in carrying out the histopathological evaluation of skin lesions. The extensive contributions of Mr. H. H. Hechter in the statistical analyses of the data, and of Mr. C. A. Sondhaus of the NRDLin dosage calculations are gratefully acknowledged. ae aan . ave - see
