At 0900 two helicopters departed from the Bairoko for the inital radsafe survey and two other helicopters were sent to Eneman Island with work
parties to clear debris from the airstrip.
At 1000, radiation of
w in-
tensity, except at the crater, was reported. The lagoon was report
clear
by the USS Belle Grove, and at 1315 ships began to reenter the lagopn.
Bikini was not heavily contaminated after ROMEO, since the win
ried most of the radioactivity to the northwest.

Data from the frek-
floating buoys of Project 2.5 were not sufficient to produce reliable contours.
Figure 74 presents estimates of the fallout pattern and inténsity
derived from these data.
The maximum intensity was observed at 35
i (65
km) from ground zero; this corresponded to a land reading of 435 R/§r at
H+l
(Reference 40).
