To provide the maximum exposure duration for dosimeters, such devices
will be put in place on Bikini and Enyu Islands upon arrival at the Atoll.
It is desirable to establish five or more measurement locations for each
potential village site with dosimeters placed at the surface and three feet
above the surface.
Dosimeters are to be placed in each remaining structure
such as buildings and bunkers that could be used for shelters.
These devices
will be recovered just prior to departure and will be transported to USNRDL
for processing (readout) by the fastest available means.

Present plans/call for a single visit to ten or more additional islands
in Bikini Atoll although it may be practical to modify the tentative schedule
such that certain islands may be visited more than once.
A single short visit
generally rules out use of devices that require an extended exposure period.
There may be some exception for any area wherein portable instruments indicate
levels sufficiently high that a readable exposure may be accumulated during
the planned stay time on the island.
Therefore, exposure levels on islands

with a one day visit will be documented primarily through measurements by portable hand held instruments.
A number of measurements sufficient to cover the
area of the island and providing redundancy in the data will be taken.
