CONCLUSIONS and RECOMMENDATIONS
4.1 CONCLUSIONS
Histories were obtained for initial-gamma dose rate at 550 and 750 yards from ground zero
until the intensity fell below the lower recording threshold of the instruments. After adjusting
the measured data, agreement was obtained with Lassen data from Operation Plumbbob and
computed data obtained from the existing theoretical technique.
The measurements of total-initial-gamma dose were in substantial agreement with theoretical
predictions. The present methods of predictions for fractional-kiloton weapons appear valid. At
110 yards, an average dose of 243 r was measured; at 310 yards, 18 r was measured.
The neutron-induced activity at 30 yards from ground zero was
negligible when conipared to
dose rates from fission product decay.
The field test of a prototype of the standard Air Force
gamma-radiation-fallout detector
(designated MG-3) was successful.

4.2 RECOMMENDATIONS
With the increasing importance of fractional-kiloton warheads
in the weapon inventory, additional measurements of initial-gamma dose rate versus time
from a full-scale yield of proposed
warheads would be highly desirable.
