REMARKS:
Contamination of the islands of Eniwetok atoll was generally masked
by the contamination resulting from the earlier Mike shot.
The dose
rates indicated in figure 102 are estimates based upon readings taken
from helicopters flying 25 feet above the ground.
The estimates are
corrected for dose-rate levels existing on D-1l.
