Again, I should like to point to the wide range of permissib] opinion which exists in the study of human genetics and the need, Until further scientific therefore, for further research, knowledge is acquired, it is not permissable to indulge in categorical statements as to the long range genetic effects of radiation, However, on the basis of factual evidence we now possess, the Commission's scientific advisers conclude that the amount of radiation exposure from all nuclear tests up to now is such a small fraction of the exposure which occurs naturally from the soil, water and air it 1s impossible to expect to detect a genetic change, even over the area of an entire population of many million people, The medical and biological advisers of the Atomic Energy Commission are of the belief that the possibility of serious genetic effects from the small amount of additional radiation produced by the atomic testing program is remote, unless an assumption is made that the human race is poised on such a delicate genetic balance that any amount of radiation, no matter how small, might upset the equilibrium, There appears to be no seitentific basis for such an assumption, However, as stated, the Commission is continuing its thorough studies in this field and its findings will be reported to the Americen people. The eppraisal which the National Academy of Sciences will undertake will be broad in ~ JO -~ ee
