253 leach this down into the soll. CONALDSON: Is it complex and fixed? It dcesn't leach to any degree, It stays pretty well fixed, It's accumulated in the algae in that upper layer, isn't it? DONALDSON: WOLFE; end, That is as that radioautograph shows, Yes, And the algae are only in about the upper Below that it's apparently too dark. CASARETT: wo or nw a VOLFE: Maybe we can ask the same question about 10 man as we just did about other organisiis , il studies could be done to show that they had this radiation 12 exposure, and so far it seems that the cesium-137 would re- 13 veal the exposure, 14 Studies do in two ways by nodules or ablation and the beta 15 burns, the scar are depignentation, or the nevi, 16 give some clues as to what may be looked for in animals or 17 plants? 18 concentrated in the tissue of birds or plants? i9 genetics has already been rentioned, Cytogenetic studies do, What mineral ‘The thyroid Does this For example, where are these radioactive isotopes 20 The cyto- Does this give some clues from man who can be studied 21 in greater detail as to where you might look in other organ- 22 isms? 23 CONARD: This is going backwards, isn't? We're 2k usually trying to extrapolate from animals to man and now 25 we're going backwards. 26 CASARETT: 27 CONARD: 28 here, 29 about it. 30 You can do it both ways. I suppose there would be some correlation It would depend on the animal. TAYLOR: We hadn't thought Is there any animal study that correlates 2 $ 31 with the observation of malformations of human children that 32 were in the fetal atate two or three months or so when the 33 irradiaticn took place? Is there any animal counterpart of 5 ‘3 n
