Edington, Associate Director for ‘Research and Development Programs, DBER KARYOTYPE STUDIES OF MARSHALLESE POPULATIONS Your comments on the Eniwetok Radiological Survey Report outline vaises the question of karyotype studies: The Bikineans and then some years later the Eniwetokese (Populations of hundreds in both cases) will be returning to their native atolls and experiencing a relatively abrupt and well-defined doubling of population radiation exposure rate, As you well know, a karyotype study of Marshallese populations would be logistically difficult, expensive and, perhaps, impossible for political reasons and lack of qualified personnel. I feel strongly, however, that we should have an evaluation of the potential scientific value of such a study and would urge thatBiomedical Programs staff undertakeaserious study of. this matter, and“provide. “youwith”recommendations regarding the scientific merits. pet Nathaniel EF.
