PROPOSED ACTION could be done to learn more, but that no conclusions (in the form of numbers) should be drawn. It was DR. GLASS' (continued ) opinion that the ACBM should report only to the AEC with no recommendation regarding a public statement and that she statement should perhaps be made by groups, such as the NAS. DR. WARREN suggested a further look at tangible things, such as the results of experimentation with mice and dogs apd also a careful review of what is known about man, for example, his tolernce to radium. He expressed the opinion that predictions were too far from the tangible. A lengthy discussion followed regarding the effects of radium on humans, both from the carcinogenic as well as the genetic point of view. The contents of the latest semi-annual report as well as further progress by NAS Committees were discussed. DR. CANTRIL suggested keeping in touch with NAS Committee progress before writing any report and that @ correlation in point of view and in number would be desirable before making any quotations to the press. DR. DUNHAM asked the Committee if any members felt that the situation was now dangerous. DR. GLASS responded that it may be but that there were not enough facts at hand to reach a decision. A discussion as to what should be considered dangerous followed with suggested estimates of allowable percentage increases of bone tumors and lung cancer. DR. CANPRIL expressed the opinion that the immediate concern of the ACBM is whether a), investigation is being carried out adequately and »b), that uninterpreted data be presented to the scientific community. He believed that the NAS should interpret the data and that the NAS should be asked if the investigation is adequate. A discussion followed between DR. GLASS and DR. WARREN about the desirability of challenging public statements of colleagues and the dangers of over-emphasis in statements by recognized scientists. The meeting was adjourned at approximately 11:30 p.m..
