The 5041 sempling program ts deg
distribution of the activity of varid
bné Enev Islands of the Biking Atoll, Every possible cffort will be made
to integrate this sampling program with previous programs to avotd undve
duplication of effort. The actual nunder of samples and their specific
collection sites will be a function of (1) the expected activity levels,
(2}. future home-construction plans, (3) future agriculture? plans, (4) the
aerial survey results or any other moasure of the varisbility fn the gamns
exposure rates, end (&) the number and locations of recent toil somles
collected by other proorams.
Kethods and Measurements:
Two types of sot) samples will be goliected for analysis: (I) 3
15-cm-deep surface core sample of 60 cm* brea, and (7) 5 profile cojlection |
area
based up on sidewall sampling ip 6 trench in which samples of 300 cy
are co} ected at 15 cm depth increments to a tote? depth of 90 cm. for ..
purposes of planning the survey, Bikint Island uy be divided into the north,
central, and sovth sections along the respective second base line roads, Encu
nay be divided into the north and south sections divided by the airstrip.

Note thst a mejor fraction of the sur
foce samples will be collected within the central section of Biking Istend. hts is due to the relatively higher and more varlable gamma exposure rates
in this area ond to the fact that a major fraction of the returning Bikintans
will most likely reside within this section. Only 3 few profile samples are
planned in this area because severel samples have already been collected
during previous surveys. The north and sovth sections of Bikini Istend and
a1} of Lncu exhibit relatively lower contanination levels; hence, the sampling
Oensity fis lower. Special emphasts, however, will be given to the lagoon |
side of Enew since future homes msy be erected in this ares.
