CRAPIER & CONCLUBIONS hl RESIDUAL-GAIMA EXPOSGUIE RATE The results of the residual-game-exposure-rate measurenents ehov that for some devices the decay exponent varies vith both the type of device anf the station location. ‘The decay exponent was fairly wiform for different station locations for Shot Zuni (1.04 to 1.18) ané rather variable for various station locations for Shot Bavajo (1.07 to 1.39). Although no special significance is attached, the spread of values forthe decay exponentseems to be greater when the averagevalue is high sad emller when the average value is low. Toe residual instrumentation systex performed at about 50 percent of its capability. This isexplained bythe failure of the recorders, which were notdesigned as field instruments and vere used because no others vere available. ‘There vere no knowfailures of the Conrad detectors. 4.2 INITIAL-GAMMA EXPOSURE RATE Figures 3.27 and 3.96 show that approximtely tvo-thinis of the total initial-geom exposure was delivered after the arrival of the shock front. Insufficient initial game rete or dose data is available to allow independent comparison vith published scaling laws. Figures 3.23 anc 3.x indicate reasonable agreement of both Redwing Projecta 2.1 ead sf. Louw 2.2.0 2.2 data pointe with Ti 23-200; however, measured dove-versus-distance curves 74
