The authors wish to express their sincere appreciation to those whoparticipated and others too numerous to mention whose efforts contributed to the successful completion of the survey. We are particularly grateful to Dr. C. L. Dunham and his staff of the Division of Biology and Medicine of the Atomic Energy Commission and Dr. L. E. Farr and manyothers at the Brookhaven National Laboratory for their enthusiastic support. The support of the Department of the Navyin furnishing an LST and transportation of the teamas well as the assistance of the staff of the Naval Medical Research Institute, the Naval Radiological Defense Laboratory, the Commander-in-Chief of the Pacific Fleet, Naval Station Kwajalein, and theofficers and men of the LST, Plumas County, was vital to the success of the Mission. In the Marshall Islands we greatly appreciate the splendidassistance of the Trust Territory officials, particularly Mr. Maynard Neas, Drs. John Iaman, Dr. A.
