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.
