IX On earlier tests commncation failure occasionally occurred, and sampling pilots had to operate without control. Some were of such high calibre and competence that they managed to obtain acceptable samples in spite of the communication failure." Concerning radiation dosage, Mr. Moore offered this comment: 25 Preplanning has always been so well done that the dosage to be received is known before the mission starts, The same for ground personnel and natives was not always true, although no serious and long-lasting illnesses have resulted from unplanned fallout or routine decontamination, yy) » But in our earlier operations es DE} established that we had been operating for years with a larger percentage of luck than we knew, Local wind situation has since been recognized as of extreme importance us fooled us on lout and yield. all weather had been predicted accurate winds blew fallout directly over the troop and operational areas, Fortunately it was not of sufficient intensity. to require evacuation or extraordinary precautions, However, the weather people, after that incident, also forecast the local winds, Lack was also with us on another occasion. Of all the planes scheduled to participate on that shot, two aborted. Had they not aborted, they would have been directly over the detonation when it occurred, Again, great care was taken to package and return samples obtained to Los Alamos Scientific Laboratory with greatest possible speed and safety. Immediately the sampling aircraft landed, samples were removed, rolled into tubes and inserted into the lead "pigs" for their flight to LASL, Sample-carrying couriers were marked internally so that neither crew or passengers would get close enough to the pigs to receive more than one week's tolerance dosage during flight. Sample couriers flew straight through, with only a 20-minute stop at Hickam AFB, Hawaii, for refueling. Upon arrival at LASE, the samples were immediately removed from the pigs, placed in a solution of strong acids on a quartz flask in the "hot" chambers and filter paper and filtered material both completely dissolved, The resulting 193 APOLIHO SWEH-~2-003; yl? y Be.
