SESSION ON THE STRONTIUM-90 FALLOUT PROBLEM (Continuation of Discussions at Special Meeting) DR. FAILLA opened the meeting by presenting the problem. A special meeting was held in Washington on December 26, 1956 for the purpose of - considering the strontium-90 fallout question, but no decisions were reached. DR. GLASS pointed out two things that happened at the meeting which prevented STATUS OF PROBLEM reaching a decision. They were, the statement by Commissioner Murray that the weapons testing program for the coming year was already decided upon and the comment by Admiral Strauss that there was no great urgency for a statement by the Committee. DR. DUNHAM commented that Admiral Strauss had not been aware of the purpose of the special meeting when he arrived to greet the members and had later expressed the opinion that he did not intend to discourage the Committee from studying the problem and making any recommendations it saw fit. Dr. Failla said that the problem exists in the mind of the public and that some statement should be made by the AEC as to what is the true situation with regard to the strontium-90 hazard. in response to a question by Dr. Dunham as to whether the Committee had in fact come to any decision, DR. WARREN stated the need for further information as to the degree of accuracy of the various analyses of strontium in the bone. This stimulated a lengthy discussion of the methods of sampling and the AVATLABLE AND REQUIRED DATA analysis and the Committee was reassured by DR. DUNHAM and DR. WESTERN that there was very little likelihood that any significant errors involved in the bone analyses which are currently being done by five or six different laboratories, including one in England. The desirability of offering spiked samples to the various laboratories for intercomparison was discussed and DR. WESTERN agreed to follow this up.» He indicated that recent statements by Dr. Comar would tend to alter Merril Eisenbud's estimates of ultimate maximum uptake by a factor of 2 to 5 in a downward direction. DR. WESTERN pointed out that these exact numbers are relatively unimportant, but that the entire problem should be redefined in order to clarify understanding in three general classes of the public; the general non-scientific public, the general scientific CLARIFICATION OF PROBLEM public and the scientific public informed with regard to radiation. Such a redefinition of the problem would consider the pertinent criteria; such as, genetic effect, bone cancer, leukemia and lifespan. The questions should be considered as to what is safe and unsafe or what is acceptable or unacceptable and also what would be the alternative to a normally unacceptable level. -4.
