cistance from the atolls (Keference 5), Again they represent the best
data available and, in the atsence of contrary evidence, had to be
taken as typical of the fallout on the islands,

DOSE-ENERGY DISTRIBUTIONS FOR PLANE SOURCE CEOMETRY
Te campute the proportion of total airdose due to a given energy
interval in the degraded spectrum which resulted from the cpectrum of
the original sample, the dose from the spectrum cue to the exitter dis-
tributed as an infinite plane source was calculated by surming the
contributions over all path lengths in air, By dividing the original
H+ 94 hour spectmm into 13 erergy regions and carrying out this froe-
ess (heference 7) for each, a cumulative dose versus energy curve
resulted,
The cumulative doses are siven in Tables L.1, 4.2, and h.3.
From these curves, a differential histoeram of percent cose versus
energy interval was determined which represents the percent of dose
.
