BRITISH REQUEST ON SOLUBILITY OF FALLOUT MATERIAL
The data most closely identified with the problem raised in Col.
Stewart's letter is related to the surface burst of March 1, 1954
on & coral islend,
Although considerable data were collected on
fallout from this shot, including island water activity, solubility
studies were minimal and not carried out until 94 months or later
after the detonation, These are summarized in the attached table,
The solubility of fallout material shortly after a burst would be
expected to be somewhat greater,
Whereas, the uncertainties in
these data ere obvious, they do strongly indicate a very significant
difference in solubility from detonations over sandy soils,
