403027 March Dr. John N. Wolfe, vs LOL Chief Envirormental Sciences Branch Division of Blology and Medicine U. S. Atomic Energy Commission Washington 25, D. C. Dear Dr. Wolfe: You have asked for our "reaction" to the “Addendum on Vegetation Rongelapese. to the 1960 medical report on the The first reaction was one of surprise at the inclusion of such a section in the medical report. The second reaction, shared by Ralph Palumbo who has been studying the vegetation at Imiwetok and Dick Walker the plant physiologist from the botary department who has been participating in the Rongelap studies, was that While the observations reported are correct. as far as they go, the implication that radiation has been the primary Causative factor: is without foundatio.. and is scarcely negated by the general statements in the pe- nultimate paragraph (Ralph is also sending you his com- ments). Unfortunately, the emphasis on radiation efrects is given added credence merely by the inclusion of the addendum in a report by specialists in the area of medical aspects of radiation effects. This is quite a different proposition then the publication of similar material by Fosberg who does not purpert to be a radiation expert. Fosberg at least has a backlog of observations recorded from other atolls, either as author or editor, from whic:. he has implicated such other factors as drought and the activities of birds as being of pri- mary importance (there was no fallout in those areas) in causing deleterious effects to the vegetation. When more data are available he has the background to enable him to reinterpret his observations and either change his susoicions or affirm them as conclusive. Such ew reinterpretation would presumably be communicatec through the same media Fosberg has used previously and the record would be clean. BEST COPY AVAILABLE
