Fig. 6—The calculated and observed gamma dose rate at H+ lhrasa
function of distance along the hot line of the Sedan pattern (diagnostic
calculation).
Figure 7 shows the calculated (H + 1)-hr dose rate vs, distance curve
from the model, and the observed (H + 1)-hr dose rate vs. distance. As
was previously mentioned, the value of F, used in the cratering-falloutmodel calculation was 0.05. If a value of 0.04 for F, (as reported in
Ref, 4) had been used, the agreement between the calculated (H + 1)-hr
dose rate and the obServed (H + 1)-hr dose ratevs. distance would have
been better than shown in Fig. 7.
Recently effort has been expended to obtain machine capability of
plotting the calculated (H + 1)-hr dose-rate patterns for an arbitrarily
selected interval of dose rate. Figure 8 shows the machine-plotted doserate pattern for the Danny Boy diagnostic calculation. The computer-
