2 Ph2G26> RADIATION STANDARDS, INCLUDING FALLOUT 171 Representative Hosmer. Were you complaining about the long extension of the moratorium on testing or what? Is that what you were implying? Dr. Lancuam. No. I would just like to know, are we gaining significantly by holding additionaltests or is further weapons testing essential to the defense of this country? If it is, there is no question but what we should doit. Representative Hosmer. I guess somebody evaluated it and found it was worth while. Dr. Laneuam. Undoubtedly they must have. Chairman Ho.trterp. I am sure that the President and his advisers looked into this matter very carefully. I was present at some of the conferences that took place. I have also been present. in executive hearings where evaluations of the debris from the Russian tests were analyzed and the meaning was conveyed to the members of this committee which indicated in some instances a sophistication which did not exist in the 1958 test. The problem of defending our Nation, of course, is involved in the President’s decision. The President has expressed himself more than once that he would like to see testing stopped, that he would walk the last mile to obtain a cessation of testing and establishment of a disarmament—a real disarmament in the world—but lacking the progress in these fields due to what many of us who have watched the negotiations believe to be the recalcitrance of the Russian Soviets and their absolute refusal to allow anything that approached a guaranteed inspection system, and in the face of the tests which indicate capability of improvementin military capability to attack this free constitutional government which webelieve in, the President and his advisers have made this decision that it is necessary. It has not been made idly. It has been made after a great many months of soul searching and the best scientific advice available. So I can assure you as one member of this committee that the resumption of tests was decided to be necessary. It was a reluctant and long-delayed decision. But it was made on the basis that the security of our Nation was involved in making that decision. Dr. Laneram. This was not said in the way of criticism at all. It was said to imply that as far as I can see with the risk this small, and a potential importance so great, that the President had no alternative. Representative Price. Dr. Langham, on page 4 of your complete statement, you state that animal experiments have proved unequivocally that enough strontium in the skeleton will prove bone cancer and other skeletal pathology. Youalso state that the amount to do this in man is not known. Whatis presently being done in this area to give us this information and how muchlonger will it be to complete this work. Dr, LaNneHam. There are any number of animal experiments under way involving the tumorgenic properties of strontium 89 and 90 and radiations of other types. We may knoweventually how much of this material it takes to produce a bone malignancy in a rat or mouse or other laboratory animal. We maynever know how muchit takes to ‘86853 O—462-—pt. 112 CASEBESTLOBonesSURESPeteITTaieRRM
