covering the time period up theu June 62.
waa On December 15, George Cowan sent a memorandum to Bradbury addressing the
letter from Bethe on 5 December.
As for prompt sampling on underground shots,
the experience to date since September has been very poor but the Fisher event
has yielded the first useful prompt radiochemical sample in the multi-filoton
region known to Cowan.
As for a delayed sampling, the time delay has been one
to two months and may come down to approximately three weeks and is reasonably
accurate in determining yield for single stage devices but for multi-stage
diagnostics determinations are relatively poor.
LASL drill-back problems
In contrast with Livermores has been greater since it is more difficult to
drill
in uncompacted alluvium than it is in compacted fuff.
As for the question
of tunnels versus holes, Cowan feels Bethe is making his conclusions based on
certain recent overly optimistic LRL's statements and that the stemming problem’
in tunnels still exists whereas the only significant advantage of tunnels over
holes is the added ease of line-of-sight experiments and does not exist in the
realm of sample recovery.
