X(r) 2 Y(r)
Figure 1.2 is a plot of Y(r) versus X(r) calculated by assuming that the relative importance of build-up is inversely proportional to X(r). Thatis,
X(r) q(x) = a(X)p,
where a(X)r, is the build-up for equilibrium spectrum. The correction factor shown is
for a low H content and is therefore conservative. Thatis, errors will occur from
overestimating, not underestimating, dose rates. For modern weapons with small
amounts of high explosive, X(r) will probably never exceed three.
