Overpressures were measured with ground baffles and
pitot-static gages. A precursor formed but died out at
an unusually high overpressure of between 35 and 55 psi.
The usual high dynamic pressures associated with
precursors were observed. Outside of the limited region
in which the precursor existed, the overpressure and
dynamic pressure measurements were in agreement with

950. ABSTRACT
Measurements of the intensity of fallout gamma
radiation as a function of time and distance from the
Ivy Mike and King shots are reported. Instruments were
placed around Eniwetok Atoll and at several atolls ina
southerly semicircle with respect to Eniwetok. Contrary
to expectations the winds prevailing at the time of the
Mike shot were south or southeasterly and ro fallout
gamma radiation with the limits of detectability was
measured at any location other than Eniwetok. The gamma
radiation measured on Eniwetok Atoll was considered
normal fission fragment radiation which decayed with a
