rag Pd Y was impressed by what Mr. Solomon said, namely that the sampling thing, by ites nature, had to be a developing thing and it Just seens to me that worldwide aspect could very reasonably be put LIBSYs fhe only reason that the deyelonment will ever go is the worldwide assay. That is my answer. I would like to suggsst that we break off for lunch in two or threa minutes. a detection. proven. Let me just tell you what I think we can do on Of course all of this has to be worked out and Sut the detectable levels, of course this means that you are going to work hardest on these. The lower limit, I would say, is about 1 dpm and this to be contained in any ameunt of aampls up to 100 pounds. How what is one dpm ~- that is one- millionth of human tellerance. The person whe {9 just beginning te feel the effects of Strontiun; it is contained in one millogran of ealcium in his bedy. In other wrds, there is absolutely no difficulty in determining Strontium in buman bodies if 1+ gets any where near tolerance. Row who knows what it is now? [| den'% even know whet ¢alculations can be made; [ can't even guess. Is anyone willing to guess what it aight be now? If you say that it is « thousandth of Imman telerance at the present time then one gras of caloium is the minimum you will be needing for this saaple. world, Jou, the present asount of 3trontiua in the The present assay; well, we say a 90 kiloton bom gives i gram of Strontium per AT roughly. with a 5% fesion yield we have this many Strontium 90 atoma produced from kilcten soxmb and DOE ARCHIVES
