37 procedures instituted whenever possible. The examinations show somefindings persisting in the exposed people which need to be carefully fol- lowed. These include incomplete recovery ofcertain blood elements to levels found in the unexposed people, retardation of growth and developmentin some of the irradiated children, and pigmented changesat thesites of radiation burns of the skin. Recognizing the importance of these surveys, the Trust Territory of the Pacific Islands and the U.S. Atomic Energy Commission have agreed that annual medical surveys of the Marshallese people exposed to fallout in 1954 should continue indcfinitely. Company of Texas, and Dr. Stewart Shippey at the Kwajalein Hospital were all extremely helpful. At Brookhaven National Laboratary, contributions were made by manyindividuals in many departments including Medical, Instrumentation and Health Physics, Photography and Graphic Arts, the Shipping Section, and others. We are grateful to the following people for their support and advice: Dr. Maurice Goldhaber, Director; Dr. Lee E. Farr, Chairman of the Medical Department, and others in this department including Drs. D. D. Van Slyke, V. P. Bond, E. P. Cronkite, J. S. Robertson, S. Cohn, L. M. Schiffer, R. A. Love, L. K.
