RETURN OF RONGELAPESE “The drop in lymphocytes is early and profound. Little or no evidence of recovery may be apparent several months after exposure, and return to normal levels may not occur for months or years. “The platelet count, unlike the fluctuating total leukocyte count, falls in a regular fashion and reaches a low on the 30th day. Some recovery is evident early; however, as with the other elements, recovery may not be complete several months after exposure... .’’* 47 At one year later the Marshallese were reexamined with the following conclusions: ‘(In general, the Marshallese have recovered satisfactorily from the radiation injury received during March 1954. Visible residual effects are limited to a few areas of depigmentation and two small, distinct scars from radiation burns, one of which will possibly require plastic repair. ‘Neutrophil values have returned to the normal range of the control population.

The symptoms suggested that, “These findings can best be explained on the basis of a cerebrovascular accident.” * An il-year old boy was hospitalized with acute rheumatic fever and cardiac decompensation. “The diagnosis of rheumatic heart disease with mitral stenosis and insufficiency was substantiated and at the time of the examination, the boy was fully active without evidence of decompensation.” 4 A 46-year old man died on May 13, 1956, of heart failure. It was concluded that, ‘With the exception of the residual of skin lesions, none of the clinical findings in the exposed group could be attributed to the effects o irradiation.” In regard to skin lesions it was reported, “Some residual lesions are present in the Rongelap people. ... The majonty of all show improvement. Almost all of the early superficial lesions are completely healed at this time without any apparent residual changes. . There appears to be no evidence of any change which would suggest malignancy.” Urinalvsis was made about two years after the March 1954 detonation, for people living on Utirik and Likiep Islands, for the Rongelapese living on Majuro Island and for personnel at HASL (Table 47).°"* It is recognized that these are limited data, but the values for the HASL group show the general world-wide distribution of the fallout debris, and indicates that the Sr® activities found in the Pacific group are probably more the result of living in
