varied from 0.045 x 10°7 to 0.070 x 10°7, For samples 251.03 and 251.04
on Shot 1, using only the island survey data (as corrected to 1 hr by
Project 2,58)fave a ratio of 0,045 x 10"7 to 0,064 x 107 and 0.043 x 10°7
to 0.058 x 10°’
while other ipland station samples gave ratios varying
from 0.01 x 1077 to 1.0 x 107’
when similarly compared. Excepting for
those noted in Table 3.21, a factor 0.053 x 10°7 was used to estimate the
field reading from the total gamma count.
If the assumption of complete
mixing of the three components with the radioactive device components is
valid and if the sampling techniques are sound so that the sample is a
representation of the over-all fallout in the particuler area, then the
ratio of the field radiation to the surface density of the tracer fallout
components should be a constant for each shot. The comparisons as given
in Table 3.21 show lange variations instead of constancy, Actual field
readings were available only for Shot 1 island stations where the sample
recovery was actually the most questionable, The extent of error in the
