FFICIAL USI ONL -3the Division of Environmental Health Sciences (DEHS), Research Triangle, North Careclina and the National Center of Urban Health and Industrial Medicine 1% Ciscinnatt. Dr. L. W. Tettle, of the Division of Environmental Health Sciences has been acting as coordinator for their research effort. In collaboration with DEHS the AEC has entered into two interagency agreements, Battelle-Northwest and Rochester, for additional research directed toward the “Biological Effects of Radon and Radon Daughters." Since the last ACBM meering an additional contract dealing with the uranium mine problem had been initiated by DBM, This work is with Dr. Geno Saccomanno az Grand Junctior, Colerado, and consists of the establishment of a tumor registry, a follow-up on the exfoliative cytologic changes in miners‘ spucum afier they have been reassigned from underground mining, and an effore by Dr. Saccomanno with several other pathologists to further evaluate tne exfolrative cytologic technique. Uranium Miner Research. Dr. Lough reported that the development of instruments needed im conmmection with estimating exposure to radon daughters in uranium mines 1s proceeding along two lines: 1) development of am improved inscriument to measure the radon daughter concentration in mine air ~- tne "Inetaat Working Level Merer' developed by Dr. Schroeder, MIT, is considered outstanding; 2) the "Personal Dosimeter" of which several types have been developed. These devices are all intended to estimate the integrated exposure of the wearer to radon daughters and upon appropriate read-out yield the exposure in working level weeks of months. All of these devices are under examination in the laboratory and mines. lt is hoped that the field testing will be completed by January 1, 1969. StatusofABCC. The current status of the Atomic Bomb Casualty Commission was described by Dr. Storer. A brief history of the scientific program was presented which indi.ated that while for the first 20 years of operation the findings were essentially negative (except for leukemia incidence) there are mow emetging positive data indicating an increased incidence of thyroid, breast, and lung cancer and an increased death rate in the heavily exposed survivors. Despite the extreme scientific importance of the program DBM is now being squeezed by inflation in Japan on the one hand and by the balance of payments problem on the cther either to effect a reduction in personnel at ABCC or to induce the Japanese to increase their scientitic, administrative and financial participation. DBM has elected to pursue the latter alternative initially and steps are being taken to Open negotiations with the Government of Japar to see whether they will agree to am increased role in ABCC affairs. international Biological Program.
