SESSION UI 14} in auch a case strontium-90 is the main source of radiation to these people? CONARD: I think itis. radiation point of view. It's probably the main hazard from a I still contend that this amall selected group of people is going to be faced with many more problems that far outweigh possible contamination from strontium-90. AYRES: [ accept that, but I wanted to bring out these points. CONARD: The last item I have here is protection, survival, and recovery measures. I don't think I need to emphasize to this group the fact that taking shelter in either homes or basements or fallout shelters is quite protective. I think that one might want to consider such things as the use of the stable isotopes, perhaps strontium and particularly iodine, during this acute period. It only takes about three to four milligrams of iodine a day in the adult to suppress the absorption of the iodine uptake of the gland, two to three milligrams in the case of children. 1 don't think it would be unreasonable to have a little Lugol's solution, potassium iodine, available to add to the diet and perhaps stable strontium or calcium. WARREN: How much are we getting now in the salt? At one time we had a lot of hypothyroidism and myxedema around the country and there was a dcive to put increased iodine portions in the salt. I think the Morton Salt Company has done that, but I'm not certain. FREMONT-SMITH: They have. store. We do regularly. WARREN: Yes, but is the iodine still added? FREMONT-SMITH: CONARD: In fact, you buy it in the grocery So it says. You can't taste it, but it says so. It's a small amount, a very small amount. BUSTAD: I would exercise caution, I think, in recommending stable strontium because I think the amounts that you would require to really alfect the uptake would be toxic. it? AYRES: Anystable calcium would be just about as good, wouldn't CONARD: That's right.
