Figure 53 shows the track of the Daigo Fukur the P2V abort point from the first account. Maru and Figure 60 shows a p§ot of the reconstructed fallout pattern at the approximate time the P2V abdrted. Cloud sampling began 2 hours after the detonation and continued for 5 hours, with aircraft working from 30,000 to 45,000 feet on the south and southeast edge of the cloud (9.1 taj 13.7 km) (Reference 16, p. K-~#7). This sampling was performed close to the burst point and, although the sampler aircraft were in contact with radsafe personnel on the Eskes, little concerning the picture of the cloud's overall movement was leBrned. Twelve or fourteen F-84s and two B-36s were used in this sampling] with one B-36 acting as controller. Fallout reached some elements of the fleet later, depending og positions. The USS Gypsy did not receive fallout until 1400 and units were less contaminated. 213 their qome
