with a survey of the lagoon area.
On this latter mission they followed
a prescribed course, and the same system of recording intensities
prevailed.
One of the high priority missions on X-RAY day was that of the
crater sample recovery.
This party proceeded to ZERO island by LCM at
H=-plus-3 hours and beached near a revetment protecting the crater
sample recovery tank.
They were met there byS§@ii}emem who had arrived
on the island from Eniwetok by helicopter.
The tank was guided into the
crater by remote control from a helicopter to scoop out earth samples,
In the event that the helicopter and its standby were unable to control
the tank the LCM was prepared to act as the remote control station.
The tank made two trips into the crater and returned with samples but
these were not considered as having sufficiently high radiation intensities,
The tank was directed into the crater for the third time but
became bogged down.
The most representative of the samples obtained
was divided; the major part for QiaREzeaayme laboratory on Eniwetok
Island and the other for the TG-7.6 laboratory aboard the BAIROKO for
_ analysis in connection with technical measurements projects being
carried out in the interest of radiological safety.
The ZERO island radiological safety survey was started on X-plus-1
day.
Intensity readings were taken at various spots on the island which
had been marked with numbered stakes,
These intensity readings were
immediately transmitted in code via radio to RadOps on the CVE where
iso-intensity lines were then plotted on overlays of island charts.
On X~plus-1 numerous biological samples Were collected and
