was evaluated

from appropriate log-log plots and found to be in the
range 1.1 to 2.03. This range of values is larger than
that expected from thermal-neutron fission.

A generalized fall-out forecasting technique is
presented with detailed computations of input parameters
which were used at Eniwetok Proving Ground. Results
obtained at a recent weapons tests are briefly discussed
by comparison of forecast fall-out with preliminary
measured data.
