Although the quantity of debris may not be scalable with other detonation parameters, knowledge of its effect on the contour ratio and its
frequency and conditions of occurrence is necessary in considering
whether or not it is sufficiently important to warrant separate treat-
ment and inclusion for consideration in decontamination investigations
and operations. _
Of the several measurement errors, the one least amenable to
treatment or reduction by careful analytical techniques is that due
to sampling bias. It will depend on type of sampler, sampling location,
sample Size, and many other factors. The parameters most seriously
affected by this bias are m and a; the value of
should not be
very sensitive.
For most collecting devices and sampling locations,
the amount of fallout collected with respect to the local terrain
(average) will be low. However, this generalization is not valid for
the island collecting stations at Operation CASTLE where the collectors
were at grade level and were not recovered for several days after shot.
In the meantime, both inert coral and fallout particles drifted into
the collectors by action of the wind.
Combining the various correction factors which, if known, would
provide a more reliable scaling function for each of the contour ratios
than those for the idealized fallout model gives

For the idealized model function, K(X,W) is equal to 1.23 x 10720 w0-038
for all values of x.
