an ia peoduced in one megaton of fleston and therefore with 800 megatons. ‘Now that is not a large number, times what we have had. that] is about 100 . Ie it necessary to teke the count of the natural strontiie which is available here in the soil here in these calculations orjnot? It is only necessary te the extent that the uptake of ontivun and calcium may be different. If we believe say take sone from this oolum, Then it would seem that the strontiu ratio in the soil is about 10 times higher then in the kx whieh contradicts Mr. Comar’s experiment, and if that r you could tolerate 10 tines as much Sr”, There is certainly enough physiological data te indicate etrontium end calofium are handled differently in the lunar body or in the animal toady and that ie the fact that at the point of mineralisation, in other words the uptake may be similar, pat if you take a rate, for instence, and pat ib on 9real low caleiue diet and try to eupploment stable strontiumfor thet calcian he become a ricketic animals he will develop rickets, the point there } the animal will absorb the strontium and will put it into part of the bene but he will not mineralise it. Thereis aldifference. Whether the difference 1s out of line completely, I doatt Inc least it does suggest that there could be a point in the of strontims on a completely adequate diet where this type pb wontt hold. os - | . .
