receive no more than l0r man-made exposure to radiation to the germ cells prior to the age of thirty no serious consequences would result, They, therefore, recommended that no one should receive a total accumulated dose to the reproduction cells of more than 50r prior to the age of thirty without clear cut medical reasons and that in any event the average exposure of populations as a whole should not exceed 10r by the age of thirty, They point out that at present about 1/3 this figure is already being used up by medical x-ray exposures many of which could with proper precautions be greatly reduced, As to occupational exposures the Committee considered this to be a limited group - no estimates were made as to its actual or potential size, As finalized in the report the recommendations are: 1, There should be a national system of keeping radiation exposures on all persons as is now practiced at AEC establishments. 2, Medical exposures to the germ cells should be reduced, 3, No more than 10r by age thirty for the population as a whole, 4, The subject should be reviewed periodically with a vlew to possible further reduction in exposure. 5. No body, however, employed, should receivenpre than 50r of exposure prior to the age of 30. 6, For special activities inherent in which are a greater liability to overexposure individuals who for one reason or other are unlikely to procreate should be sclected, 7. The state of knowledge in the field of genetics has been outrun by our knowledge in the field of physics, 8, Keep all exposures to the germ cells as low as possible for radiation exposure is generally detrimental to living cells, In essence, cn the subject, this Committee formalized the current thinking It did not come up with any new or startling conclusions or recommendations. ~ 8 - Enclosure II
