Sicin lesions were kept clean by surgical soap with excellent results lead- ing to a minimm of secondary infection and rezarkably prompt healing, ~ is felt that this eonservative regimen gave optima results and that all patients are recovering satisfactorily. 1 Detailed reports will be randered by Project 4.1 om all cases. Detailed statistical analyses will be required to properly evaluate the data derived. Urine sazples which have been analyzed in the U. $, will be combined with this study. A detailed study of characteristics of the fallout sarples, shielding properties of the measuring weather analysis will be necessary before a mre exact whole body radiation can be established. The study of lead to a meh clearer concept of dose versus effect. instruments, and dose of external all aspects should The picture of ex ternal garma radiation with a broad spectral band, combined with external beta radiation, and internal hazard makes a very complicated problem in the final report. As a corollary to immediate treatment of the personnel exposed to the radiation, evaluation of the hazard remaining upon rehabilitation anst be investigated. To that end soil and water samples, animals, plants and other comestibles are being investigated with a view of determining if and when the natives may be returned to their hone atolls. r~fN All persomel who have been involved in large dose exposures and those whose dose was small but who may have to reside in an active area should be observed over a long period of time. The first year following the teste, re-examination should be at quarterly intervals. This has been discussed with the Director, Division of Biclogy and Medicine, AEC, who advises that it is the intention of his organization to aaintaina period= de observation aystea. In summary, natives froma adjacent atolls and Americans from the Task Force were exposed to radiation in doses from a few roentgens to apprarimately 150 roentgens. Some of the more heavily irradiated may be considered to have been borderline from a standpoint of seriousness. All should recover from the effecte of the exposure. kboutesJPeaspan Colonel, Medical Corps ae Staff Surgeon
