22 The basic instrumentation is scintillation counters with recording instruments. Scoville says they are talking only of eemething like 12 channels, 12 stations, thinks they record with magnetic tape. This is long-time work like Berkeley did on Ivy. ri 2. hat about coverage in distance? Scoville: there will be a maximm iy PU £12 stations — not other atolls, but places in the atoll. %, ° ie at fall-out. No good reason to be awfully close. This is Stibictures: conerete boxes, require holes in the ground but ill not beivery close — therefore, not very complicated. OK, 12 conerete~ lined hetes. Maybe not as many as 12, they will have 2 of these on the Likerty ships. First estimate was 12 people, but Ogle points out that Berkeley did this on Ivy with 2 people for stations on the shot atoll, 2 people for off-atoll ingtrumentation. He suggests Scoville look into their system. Two people handled 15 gadgets spread on several islands. Scoville thinks thgy|will record for at least 12 hours. Ogle mentions we may well have the circumstance of appreciable activity at some of the islands fron a/previous shot, will want to turn the instrument on appreciably before the éhot in order to get a recording of the background, — sy Someone should know of wy samples back to the States. 204 This may be out completely. with 2.2, if done. 2.5 This is a big program. lem here of shipping these neutron ently, they will share facilities Discussion) ensues about whether to do anything on Exiwetok or not. Scoville t 8 not logistic effort so much. Ogle points also the meat likely to go off.

But they ‘ - These are stations which are put out and let drift, outside the lagoon. It will take a great deal of Task Force suppért..They go out to 50 miles and they are talicing of a total of 50 stati ¢tis (ineluding all stations), so maybe 30 floating stations. Ten aphece, weighing about 1000 lbs, and probably have to be put out a day before the shot. (No, Scoville reads his piece of paper, and says they are talking about 80 free-floating stations —- this was an old proposal and he) thinks the mumber can probably be cut down after they knaw of thg Bikini situation.) Scoville thinks these will be weighted to the west. to work in 24 hours before the shot. -42- im A 100-mile diameter
