where coaplaints were treated as though radiatian had not been presext. Sicin lesiona were kept clean by surgical scap with excellent results lead~ ing to a minimm of secondary infection and rezarkably prompt healing, 3 is felt that this ecnservative reginen gave optima results and that all patients are recovering satisfactorily. : Detailed reports will be randered by Project 4.1 on all cases. Detailed statistical analyses will be required to properly evaluate the data derived. Urine samples which have been analyzed in the J. $. will be corbined with this stady. A detailed study of characteristics of the fallout sazples, shielding properties of the measaring instruments, and weather analysis will be necessary before a acre exact dose of external whole body radiation can be established. The study of all aspecte should lead to a ach clearer concept of dose versus effect. The picture of exe ternal gemma radiation with a broad spectral band, coabined with external beta radiation, and internal hazard makes a very complicated proble is the final report. As @ corollary to imediate treatcent of the personnel exposed to the radiation, evaluation of the hazard remairing upon rehabilitation anst be investigated. To that end soil and water sazples, aninsls, plante and other comestibles are being investigated with a view of deternining if and when the natives may be retumed to their haze atolls. rf 411 personnel who have been involved in large dose exposares and those whose dose was small but who may bave to reside in an active area should be observed over a long period of time. The first year fallowing the tests, re-examination should be at quarterly intervals. This has been discussed with the Director, Division of Biology and Medicines, AKC, who advises that it is the intention of his organizations to maintain a period Le observation aysten. In sumary, natives froa adjacent atolls and imericans from the Task Force were exposed to radiation in doses from a few roentgens to appracimately 150 roentgens. Some of the more heavily irradiated may be considered to have been borderline from a standpoint of seriousness. £12 should recover from the effecte of the axposure. hhoJPup + ae Colonel, Medical Corps Staff Surgeca
