4a produced in one megaton of fission and therefore this corresponds with 800 megatons. Now that is not a large number, that is about 100 times what we have had. Is it necesnary to take the count of the natural strontium which is available here in the soil here in thease calculations or not? It is only necessary to the extent that the uptake of strontium and Galciium may be different. from this colum. If we believe say take some average figure Then it would seem that the strontium, calcium ratio in the soil is about 10 times higher than in the human bone which contradicts Mr. Comar's experiment, and if that wers so then you could tolerate 10 times as mich se, There is certainly enough physiological data to indicate that strontium and calolum are handled differently in the human body or 4n the animal boady and that is the fact that at the point of mineralisation, in other words the uptake may be similar, but if you take a rate, for instance, and put 1b on a real low calcium diet and try to supplement stable strontium for that calcium he will become a ricketic animal; he will develop rickets, the point there being that the animal will absorb the strontium and will put it into the protien part of the bone but he will not mineralize it. Thereis a difference. Whether the difference is out of line completely, I don't kmow but at ieast it does suggest that there could be a point in the metabolian of strontium on a completely adequate diet where this type of thing won't hold, TCE ARCHIVES
