DR. DUNHAM intz. uced the question of pulling tc_ ther all che available information on internal rediation exposure such as that received by individuals having received radium therapeutically or incidettally. INTERNALLY DEPOSITED RADIOACTIVE MATERTALS This matter had been a subject of a letter from Dr. Libby in which he suggested that Dr. Baird Hastings or Dr. A. K. Solomon might assume this responsibility. There was considerable discussion of the great need for such data which are available from many sources. The work being done by Marinelli was discussed and the need for an expanded program of this type was agreed upon.. DR. BUGHER discussed the various means of accumulating data including the work being done by Marinelli, the Los Alamos group, the Hanford group and Dr. Robley Evans of MIT and pointed out the fund of information would be very valuable in reevaluating tke permissible levels. DR. WARREN reviewed the status of the UN Scientific Committee on the Effects of Atomic Radiation which has a lively interest in this problem and is working on a compilation. This is net, however, on a crash basis but in relation to the multiple other interests of the Committee. DR. WARREN agreed that someone should be given the responsibility for assembling the available data for the ACBM but suggested that the selection of the few logical choices would result in the interruption of a vital program. He suggested that someone not actually working in the field but with the background and ability to appreciate it would be a better choice. DR. DUNHAM suggested that the first step would probably be to call a meeting of Eisenbud, Brues, Marinelli ané Hursh to review the problem and then decide the quickest and most effective approach. DR. FAILLA suggested that Dr. Robley Evans would be an appropriate choice. The long-term project at Utah was pointed out by DR. DUNHAM but he said that there would Ne no answer from this source for fifteen years. The Chairman then called upon DR. WARREN to review the second meeting of the UN Scientific Committee on the Effects of Atomic Radiation. DR. WARREN suggested that the meeting started under UNITED NATIONS SCIENTIFIC COMMITTEE ON THE EFFECTS OF ATOMIC RADIATION auspicious circumstances but deteriorated rapidiy. The most important activities had been the establish- ment of a continuing secretariat and staff. He pointed out some of the continued Russian deemphasis on genetic effects and an emphasis on neurophysiclog- ical mechanisms. He spoke of the sportanecus moticn of approval of the U. S. contribution. There had been an extensive discussion of the genetic problem and the recent United States and British reports but all of the delegates concluded that while the
