SUMMARY
The Problem
Nuclear devices fired over sea water at previous weapons
tests yielded fallout which was different from that associated
with land surface detonations.
The analytical methods pre-
viously used on dry fallout were grossly inadequate for this
slurry-like material,
Certain tests at Operation REDWINGyielded slurry-like
fallout. Therefore, new analytical methods were required
to assess the material properly.
Findings
The fallout from two seawater-surface nuclear events at
Operation REDWINGhas been analyzed using new quantitative
techniques for the measurement of chloride and slurry droplet
water content. Particle size, density and radiological properties of the slurry fallout have beenassessed satisfactorily
for the first time.
