Dear Mrs. Kepler:
Now that I am back in Pasadena I have been able to get around to answering my mail. I am afraid that your friend and her pharmacist made a big mistake in the calculations.
First, I judge that it is better to use dicalcium phosphate than calcium gluconate, although the difference is not very great. Dr. Allan Butler thinks that calcium compounds other than dicalcium phosphate might cause phosphate deficiency.
The amount of dicalcium phosphate recommended by Dr. Thomas L. Perry is a little larger than the amount given on bottles of the tablets. The Parke Davis preparation of dicalcium phosphate in tablets says dose two tablets three times a day, and since the tablets are one half gram each this would be a total of three grams per day. Dr. Perry suggests about twice as much. This can be achieved most cheaply by buying dicalcium phosphate powder, either Parke Davis or Merck. Two level teaspoonsful per day would be about the right amount to give calcium free of strontium-90 equal to the amount of contaminated calcium contained in the other food. I do not think that it is wise to overdo the addition of dicalcium phosphate to the diet.
Both Parke Davis and Merck have stated in letters that their dicalcium phosphate is free of strontium-90.
I do not know anything about the reusable strontium-90 filter that you mention in your letter. I doubt that anything practical has been devised.
My great objection to civil defense activities such as those of SRI is that they constitute a form of aggression. For example, in his article in the January 1959 issue of the Bulletin of the Atomic Scientists and also in the SRI paper Mr. Herman Kahn mentions type 3 deterrence as one of the uses of our nuclear stockpile. One form of type 3 deterrence (deterrence of minor political action) is the construction by the United States of a great system of shelters. Mr. Kahn says that this would either force the U.S.S.R. to accept a permanent position of inferiority, or to match the program by a similar program, which the U.S.S.R. would find a great burden, or perhaps to initiate nuclear attack at once. I think that the increase in our safety accompanying the small increase in probability of survival provided by the shelter program is more than outweighed by the decrease in our safety accompanied by the increased probability of nuclear war in case that this form of aggression continues.
