erplied to the sanrles collected at the lagoon stations, thereby ver-
uitting estimation of infinite field levels for those locations.
Using
the total collector as the primary source of data, ranma field contours
were thus constructed. Where total collector data were missing, activ~
ity levels obtained fron the gurmed cerer collecturs were used. AL1
data presented are baccd on the levels of activity tht would have
existed had the fallout cenosited on an infinite land plene.
The fields as indicated by the film badzes were erratic. Lecause
of poor location of tne film kodges during sampling and unsatisfactory
history during and after recovery, these data are not considered in
tais analysis.

Table 6.1 shows correlation amone the data obtained by survey
measurements on cikini Atoll anc data obteined from the total collect-.
ors and gurmed peper collectors located there. iA11 measurements have
been converted to r/hr at 1 hr for comparisons.
Figure 6.1 is an isodose rate plot of zamma activity over tne
atoll, There is inlication of a very steep gradient fron north to
South across tne lagoon. “ais sradient is also indicated in the analy-
