A little before 0,00 hours the western sky suddenly brightened. Soma of the crew saw this and some did not. In any case, they reshed out onto the deck wondoring what itdight be. About 10 rdnutes efter the flash they heard the dull sound of explosion so they decided to quit fishing and retum Lome. They wore wondering at the tlie whether it might be en atonia explosion, In any event, about 3 hours after they heard the gxplosion, the ash began to fall. This was abcut 0700, and the ash fell unt4l the afternoon. The ash accirulated on the deck to such a degree that footprints were visible and the gen- eral appearnnce vas likes frost. Some of the ash penctrated even into the slecping cuarters. Certain crew mexbers prescnted symptoms of roentgen intoxication and were nauseated. From this point on, their conditions differed individually. The ship entered port on 1, March. By that tire, syaptoms of reentcon burns were apparent. -1i- Loss of hair £59003 US DOE ARCHIVES 9. DLU94
