Samvles from Shot 3
These samples were received by the field laboratory on K+3 days;
they are described in Table 3.3. The samples contained large volumes of
liquid as a result of heavy rainfall on both the day of the shot and the
following day.
The samples consisted of a suspension of light-gray
material (like slaked lime) as did those from Shot 1;
however, they
appeared to contain a larger amount of unchanged coral sand than did
those from Shot 1, especially for the samples recovered from lagoon sta-
tions.
The triple collector on Coca Head operated exposing the bottles
for 3 hr, but the contents of the three bottles were combined before
being received. The values in the table are therefore one-third of those
determined for the total sample. Values for samples from duplicate total
collectors st station 250.05 show good agreement except in total volume
while those for station 250.07 differ by almost a factor of two, the more
radioactive sample having the lesser volume, Bottles from 250.05 read
120 and 160 mr/br at contact at K+3 days while those from 250.07 both
read 80 mr/hr. The large (and different) volumes in the 250,07 samples
would account for the relative differences in the mr/hr readings and the
total counts. The heavy rainfall decontaminated the funnels to essentially background.
