a, We mark the debris from the very high altitude
firings (whose debris would be initially entirely
above the tropopause) with tracers so as to learn the
rate and uniformity of its deposition on the earth,
b. With high-altitude sampling aircraft (now
determined to be strengthened versions of the B-57D
capable of operating up to 63,000 feet) we determine
the distribution of material (from several shots
other than the three high-altitude detonations) in
the lower cloud near zero point and as far out thereafter as possible, perhaps out to 100 miles.
ad. If funds can be made avallable, we use some
$800,000 to include in the series a 30 rocket sampling
of one firing to determine the feasibility of using
this method in later series,
e, We not undertake any large-scale effort to
determine surface samples, This would include
notifying the Navy it could proceed with its plans
to mothball the 2 YAGS which served in REDWING to
take samples in hot areas and to analyze these samples
and those taken on other vessels,
8, Dr,
Libby has recommended most strongly that the 2 YAGS
be retained in HARDTACK,
If these could be positioned on the
hot line they would give us total fallout samples for analysis
in the 2 areas where located,
There is grave question as to the
ability to correlate this data with the E-50 samples;
it is possible,
but,
if
such correlation would provide a better
quantitative estimate of the fallout at distances up to several
hundred miles from the shot.
The YAGS could analyze their own
samples and any given to them from other ships.
However,
in
connection with this possibility of using other ships for
obtaining samples, the number of vessels being made available is
tallored to other essential needs and it is improbable that any
sampling program could be accomplished from them without
additional expense,
It has been estimated that adding the 2 YAGS
to the HARDTACK program would cost about 1.5 million which the
