A... c/o Postmaster San Francisco, California Dear Bil): the BEST COPY AVAILABLE I was more than happy to get your TWX giving the results of the first day's survey. JI must admit that we were a little open-mouthed when we got the numbers down on a map and sew what had happened. Our first conclusion was that the wind had probebly played a very dirty trick on you. In no other way could we explain the emerging radiation levels on the more or less distant islands. I essume thet all of your readings were given in mr per hour, and I trust that you will continue to use the same system in the future. Yesterday we heerd of the revised estimate of yield which would help to explain the situation in part, although we still think that the wind was blowing backvards. It seems obvious that the schedule may be badly upset in the future. We essume thet the camps on Nan end Tare are out of business. We hope that in time you will give us a good description of what the hole in the reef looks like and also give us a picture of how the work in general is to be scerried on. I would also like to know what "thumbteck" 13, It does not seem to appear on any of the code lists we have around here. We assume that the entire atoll was evacuated except for the party on Nan. We will be interested to learn what sort of exposures they received. If |: “) they stayed in a bunker, they were perfectly o.k. until they emerged to . be taken off. We will, of course, bo extremely interested in getting the 4 results of subsequent surveys to learn something about the decay rate. “alt Rod Spence is due out there before long, and you might want to get from ‘ him a description of how his material differed from previous cases. It is quite interesting. . Si Shleer and company brought a 36 curie source into the cobalt room at BRL. It certeinly appears that we can use sources there of that size vith- out any serious problems. Don Muller dropped his pill down through a hole in the floor, It was finally recovered using a technique half way.between...TTA golf and polo, wees nee ee ~ Be Oe enna We will try to keep you posted on interesting news items eround bere and So trust that you will reciprocate.
