On PETER-X-Ray a token placement of different exposure materials
had been undertaken in order to test the efficiency of the methods
_employed.
No particular problems developed as a result of this
rehearsal and therefore on X-Ray-minus-four placement of materials
was commenced.
Previous to this the only film badges which had been
installed were those located in the yards and docks structures which
had to be sealed well in advance of test time.
On X-Ray-minus-four
the badges were placed in the Corps of Sngineers structures and on the
two succeeding days behind the BuShips steel and concrete shields.
