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. There will: be minimum delay in analysis. see attached schedule) 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 Panne mere: ee 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. CR UY me ws COMETHIEF! * tam, 1a he 4.
