OFFICIAL USE ON_Y -9These levels are as follows: From natural radioactivity, 100 mr/yr; from medical exposures, 50 mr/yr; from fallout radiation, 1 mr/yr; from nuclear power activities, 1 mr/yr at the perimeter of the power station; all other sources of radiation, less than 1 mr/yr. Dr. Bruner indicated that the estimates of somatic risk are now somewhat higher than those arrived at previously but the estimates of genetic risk were somewhat lower. For example, in a population exposed to 1 rad, it is expected that there would be 30,000 naturally occurring genetic defects per million offspring. The radiation exposure would induce 20 per million in the first generation and an additional 280 in the F2 through F50 generations. Dr. Totter discussed the fiscal 73 budget briefly. The Division is requesting 94.5 million but he felt that even if they obtain this amount which represents a modest increase, the funding prospects are grim because of cost increases and directed research programs. Dr. Totter reported that the hearings in the House and Senate went reasonably well although both Rep. Joe Evins and Sen. Ellender sharply questioned the wisdom of continuing the studies of the Atomic Bomb Casualty Commission. The Committee's position on this point is that the ABCC studies are invaluable and represent the best opportunity for learning about the effects of radiation in a human population. This population is unique and it is certainly hoped that it could never be duplicated. Dr. Totter then discussed some of the reorganizations that have been going on within the AEC. The regulatory side of the Agency has been reorganized into three directorates. The directorate under Les Rogers has sent the Division a long list of questions needing answers and the DBM staff will try to initiate the appropriate research to obtain these answers. Mr. H. C. Bron, who was formerly Assistant General Manager of the Commission, has left and gone to industry. A new division has been split out from the Division of Résearch called the Division of Controlled Thermonuclear Research. This move apparently was made to emphasize the Commission's interest in fusion power. Mr. Julius Rubin has been named Assistant General Manager for Environment and Safety. It is not clear how this operation will interface with the Division of Biology and Medicine. Under Mr. Rubin is a new Division of Environmental Affairs to be headed by Mr. Robert Catlin. Again, it is not clear how this Division will interface with the extensive environmental research program in the Division of Biology and Medicine. Dr. Totter then reported briefly on a conversation with Chairman Schlesinger. During the course of the conversation the: Chairman asked whether an increase in DBM's budget of 30 million would permit it to broaden its programs sufficiently to encompass energy generation in general rather than solely nuclear generation. To respond to this query, the Division approached the national laboratories for suggestions on what research was required to give a balanced program in the biomedical effects of energy generation, The laboratories sent in a stack of paper precisely 42-1/2 OFFICIAL USE ONLY
