Washington to observe the ZEBRA shot.

ran into difficulty when the wire cable became snagged somewhere in
the vicinity of the crater.
These samples were of considerable scien-
tific value and, since it was found to be impossible to recover them
by reeling in the cable by winch, a jeep was utilized and thus all but

In the period of time involved in
this mission it became apparent that the scientists and monitors
assigned to the task would soon exceed the allowable radiation exposure
tolerance. To meet this situation a quick on-the-spot reassignment of
personnel then on shore performing other missions involving lesser
radiation intensities was made.
Thus the maximum amount of work was
accomplished by utilizing these people to the limit of their exposure
allowance.
The long narrow shape of ZEBRA island, with ZERO point located at
one end, made the island survey easier than it had. been on previous
tests,
Admiral SEi@participated in this survey which was completed
on Z=plus~l by a small party.
They also collected soil samples at each
blast footing for the purpose of determining the extent of contamination.
By Z-plus~l it was apparent that the south end of ZERO island
would possibly be ready for the establishment of monitor guards and
