where complaints were treated as though radiatinn had not been present. Sicin lesions were kept clean by surgical soap with excellent results lead~ ing to a minimum of secondary infection and rerarkably prompt healing. 1% is felt that this ecnservative reginen gave optima results and that all patients are recovering satisfactorily. - Detailed reports will be rendered 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 0. S$. will be combined with this stuiy. A detailed study of characteristics of the fallout samples, shielding properties of the measuring instruments, end weather analysis will be necessary before a more exact dose of external whole body radiation can be established. The study of all aspecte shoald lead to a mmch clearer concept of dose versus effect. The picture of ex ternal garma radiation with a broad spectral band, combined with external beta radiation, and internal hazard makes a very complicated problems in the final report. As a corollary to immediate treatment of the personnel exposed to the radiation, evaluation of the hazard remaining upon rehabilitation mst be investigated. To that end soil and water samples, animals, plante and other comestibles are being investigated with a view of determining if anid when the natives may be returned to their hone atolls. Al) personnel who have been involved in large dose exposures and ([~/N those whose dose was small but who may have to reside in an active area should be cbserved 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 maintaina periodie observation aysten. In summary, natives from adjacent atolls and Americans from the Task Force were exposed to radiation in doses from a few roentgens to approximately 150 roentgens. Some of the mre heavily irradiated may ve considered to have been borderline from a standpoint of seriousness. All should recover from the effects of the exposure. khaJPeugen Colonel, Medical Corps --en Staff Surgeon
