Shot 6
A very complete array of collecting instruments was employed
for Shot 6 in the Eniwetok Lagoon and on the atoll islands.
Since tne
fallout went in a northerly direction from shot point very few of the
Stations received significant fallout. The island of Alice, approxi-
mately 3 nautical miles from surface zsro, was contaninated to 45 r/br
at 1 hr as indicated in Table 6.4.
The fallout collected was primarily upwind fallout with the
gamma field pattern defined in Fig. 5.4. The relatively low levels
about surface zero fit well witn the overall contours as determined
by Project Rete
6.2
EXTENDED FALLOUT PALTEAN FOR Sit2
The contamination of the outlying atollsi>/to the east of dikini
and the measured values of the levels of residual gamma activity following Snot 1 offered an excellent opportunity to evaluate the fallout
pattern resulting from a super weapon. A couplete analysis of Shot 1
fallout based on available field readings and a comprwhensive analysis
of the wind structure with respect to its effect on particle trajectories is presented.
6.2.1
MeasuredField Values of Resi
En
The measured values of residual gamma activity obtained by
H. Scoville, 15 were converted to r/hr at 1 ar using tne composite
gamma ionization decay curve, Fic. 5.3. One hour post detonation is
Simply a convenient reference; as will be noted in later sections,
