N in the sea which is quite completely different than the com- Ww petition that exists on land, for on land there are nutritional re mineral deficiencies that for the most part do not occur in w the sea, na about the iodine, but again generalizing, the cesium uptake won on land is directly related to the deficiency of the fat. The strontium-90 on land is an uptake we say because you have wow Then we might comment on the competition that exists the calcium deficiency, and I just mentioned a few moments ago 10 that there billions of tons of calcium in an atoll that's.som aes 4300 feet thick column that grows on the island. 12 in insoluble form and only when it's made soluble does this 13 becom in evidence. Now, this seems to refute the comment I nade earlier But this is ; So, in the sea the potassium ratio is about 360 parts 14 15 - per million and on land the calcium is about 440 parts per 16 million. 17 two of cesium or a straight atom or two of strontium in the sea; 18 we can't get excited at all about it. 19 great nuclear war, I'm going to rum out and catch myself a 20 fish and eat it entire and feel quite secure that my food 21 supply isn't in jeopardy. So it's not quite obvious that a straight atom or So when we have this 22 Well, if we may have the next slide, please, 23 AYRES: 24 May I just interrupt. That's cesium there, isn't it, Cs? 25 DONALDSON: 26 In terrestrial areas it's quite obvious that ‘in sore 27 instances there's little chance for re-vegetation or regrowth. 28 The soil is burned away; the seeds have been destroyed; the 29 entire fauna and flora one would assure in this place would 30 not be re-established. 31 Yes, The next one, please, Now, in areas where the soil 32 has not been burned and has not been removed, you see in 33 this illustration the soil core where the organic metertial Staftc “Varren DOx .CLA 2f
