Following test Yoke both Captain TAAgEY and Commander 7.
collected their materials and prepared them for shipment back to the
United States for further analysis.
The Scientific Director called a meeting of all persons involved
in making measurements of gamma radiation and neutron flux in order to
determine whether film badges could be satisfactorily used for the
measurement of gamma radiation.
This meeting proved to be extremely
fruitful and emphasized the desirability of frequent contacts between
the various groups carrying out measurements in the same fields.
As
a result of this meeting several new ideas were expressed and in order
to clarify certain points and obtain confirming data the measurements
originally planned for the Zebra shot were slightly amplified.
The
steel and concrete shields which had not been scheduled for Zebra were
relocated on Runit and in addition to placing film badges between the
shields, packets containing sulphur, arsenic and phosphorous were
inserted to measure the neutron flux.
All installations for the Zebra
shot were completed on Zebra-minus~-2-day so that only minor checking
was required on the morning of Zebra-minus-l-day.
In order to hasten
the collection of film badges and neutron detectors after the shot a
mission was scheduled for 1400 on Zebra-day with the approval
