| Low, Rad-SafeSurvey Summary *
x
“A partial Rad-Safe survey was conducted o ia
day with incomplete atoll results.
Results of this initial
survey were conclusive enough to cancel all activities for
Btl.,
First complete survey was conducted on B+2 days.
As
a@ result of wind conditions during B and B+1 day areas had
become "spotty" in nature so the extrapolated values repre-
senting the Ht+% hour readings can only be considered approximate.
These extrapolated values are based on a t7i.2
decay whereas laboratory analyses indicate a 72-8
decay
during this period, thus indicating values in excess of
those noted in Table TU-?~1.
Lagoon contamination, of consequence, was confined
to lagoon areas containing suspended sediment.
For the first
few days this area was confined to the western quarter of the
lagoon.
This radioactive sediment washed over the western
reef, out through the southwest passage or settled to the
bottom of the lagoon in a period of three days.
No alpha activity was detected in swipes about the
living areas of the Task Group.
