SUMMARY
Gamma radiation emitted by selected fallout samples
coliected at Operation REDWING was spectrometrically
analyzed for the purpose of determining its characteristics
(expressed in terms of absolute photon intensities for each
discernible gammaline) as a function of time after shot.
Since the absolute photon intensities are given and most
samples represent known fractions of the area of the fallout
collectors, one result is that dose rates in the vicinity of
the collecting site can be calculated.
Another important result of the analysis suggests that
Na becomes an increasingly important contributor to the
radiation hazard from fallout at _ times after detonation
