The contribution to world-wide fallout from these 23 firings would
be slightly greater than from REDWING, but less than halfofthat...
from CASTLE.
In the interest of reducing to the minimum the number of shots in
HARDTACK and of minimizing overall testing costs, we would plan to
fire two or three very small yield nuclear shots in the existing
tunnel at the Nevada Test Site after HARDTACK has been completed.
These would be of the same or lesser yield than the shot fired there
on September 19 and under conditions where the radioactivity would
be totally confined within the earth.
During the preparation for this test series, there will be a continual
and further review, particularly from a technical point of view, of
the necessity of each shot. This review will include an examination
by the General Advisory Committee of the scientific necessity for the
laboratories' exploratory and developmental tests.
Respectfully yours,
Qu Shaun
