RADIOLOGICAL SAFETY
A damage and radiation survey was conducted at Hl hours on i
day.
This survey covered the islands of the atoll and was conclusive enough
to limit reentry to Enyu and Airukiiji on the first day.
This survey indicated
that recontamination was extensive throughout the atoll) and lagoon both to the
east and west.
No significant secondary fall-out was encountered at Bikini as
‘a result of this detonation.
Lagoon water was heavily contaminated with radioactive sediment.
Readings of 1 r/hr were obtained at 100 feet altitude in the vicinity of sero
point on day.
shot day.
Floating objects revealed readings of 1 to 3 r/hron
Small boats and barges in Bikini = Enyn anchorage were contaminated
to a moderate degree (1 - 6 r/hr).
Lagoon flushing through ths southwest
passage materially increased radiation levels in Eniirikku - Bokororyuru areas.
Results are shown in Table 7-1,
