Orange sbot at 141,00) feet was expected to give blast results ore in
accordance with morsal scaling predictions.
Sowever, a reduction in initial
blast yield by the aechanisa of early radiacion proposed by Shelton was expected.
Using Shelton's theory, only 9 percent of raiiochemical yield should be maifest
as a blase wave.
Modified Sachs scaling yielded a prediction of 0.22 asi.
No
Separate boob material, aleraviolec or X-ray, absorption shocks vere expected
from this event.

| Peak positive and oegative phase pressure amplitudes, together with
pertinent wawe time characteristics obserwed on Johnston Island, are sham in
Table 6.1 and are plotted in Fig. 6.1.
Preliminary data points from BRL very-
low-pressure gages at Johnston Island and om the USS Boxer and USS Lansing?
are also sham in Fig. 6.1.
Arrival times from the synchronized recordings at Johnston Island show no
detecrable (= 0.01 second) difference in shock-arrival time, since the burst
was only half a mile from directly overbead from the sensing array.

depicts the blast wave pressure-time history as recorded by the CH-] gage.
