Abstract: The energy yield of an atomic explosion was determined at logn
distance by measuring the time variation of the light from the
explosion and applying an empirical formula that relates this to the
energy yield. The light was detected by an RCA 5819 photomultiplier
tube and was recorded on a magnetic-tape recorder. Measurements at Shot
Easy were made from A C-54 airplane flying at 12,500 ft at a distance
of 630 miles northwest of Eniwetok. The time to the minimum of light
intensity was 23.5 + or - 0.8 msec, corresponding to a yield of 53 + or
- 4 kt. The yield calculated from the radiochemical measurements was
46.8 + or - 1.0 kt. The peak intensity of the flash above the ambient
was measured to be 1.7 millicandles/sq ft. This experiment indicated
that energy yield can be measured at a distance greater than 630 miles
at night. Possible propagation mechanisms are discussed. Studies of the
maximum range in daylight and of improvements in technique are
suggested.

Abstract: Overseas experimentation depends upon progress of construction,
reliability of instrumentation and the overcoming of obstacles
presented by local conditions. This Operation Plan is intended to be
used as a guide for TG 7.1 personnel since it represents a record of
agreements arrived at prior to its compilation.
