in leaching the activity decreased the exposure rate by a factor
of two.
Records from Shot Flathead at 7,730 feet and from Shot Navajo
at 13,870 feet indicate that at these locations about two-thirds of
the total initial-gamas exposure wes
delivered after the arrival of
the shock front.
fhe crater-lip measurements indicated that the method vas a
feasible one; however, no usable data was obtained.
The thermal-radiation detector responded satisfactorily to a
S-Ni detonation at a distance of 20 miles.
