UNITED NATIONS SCIENTIFIC COMMITTEE ON THE EFFECTS OF ATOMIC RADIATION (continued) _ recommendations were desirabi they were also impractical. He spoke of the project being initiated to look into the recording of medical x-ray dose through the ICRP. The final report of the Committee is expected by July 1, 1958. Dr. Warren then asked Mr. Eisenbud to present his impressions becuase of his activities during the meeting. MR. EISENBUD commented on reports of very high radiation backgrounds in India and Brazil and also of the interest in the accumulation of data on the disposal of radioactive wastes in the ocean. A UN Scientific Committee resolution was passed to accuntulate records on the industrial wastes but to ignore fallout from weapons tests. DR. FAILLA asked for some of the details about the high Brazilian and Indian exposures and numbers of people involved. It appears as if there are hundreds of thousands in Brazil and four million in India subject to high radiation levels. DR. WARREN said that the Indian groups are quite clearly divided between those of the fishing population living on river banks and deltas where the monazite sand occurs and others living further inland and occupying the farming regions. This should offer sound controls between two entirely different soil backgrounds. A lengthy discussion followed in which mary suggestions were made for obtaining more data on these exposures. A problem exists, how- ever, in that the countries concerned would probably resent any aggressiveness on the part of the United States to assist in obtaining data. DR. WARREN suggests that we can be of the greatest help in the training of native scientists. DR. FAILLA discussed the request by the United Nations for the ICRP. to study the recording of x-ray exposures and that a first report would be made in April, 1958 at the next UN Scientific Committee meeting. DR. GLASS pointed out that at the radioiodine conference in Chicago, the recent estimate by the NAS Committee on exposure received during thyroid treatment was found to be incorrect as far as genetic effects are concerned because of the fact that most such radio-iodine patients are not treated unless they are at least forty years old. This contribution to the 3 r estimated by Pullman and Laughlin would probably be very small. DR. FAILLA said that Laughlin and Pullman were increasing their estimate to about 5 r but that the real value would not be known for some time.
