where [D.sub.m] is the absorbed dose in the medium surrounding the cavity, [J.sub.g] is the ionization per unit mass in the cavity, [W.sub.g] is mean energy expended in the gas to produce an ion pair, and [bar.(S / [rho][).sub.m]]/[bar.(S / [rho][).sub.g]] is the ratio of the mean electron-fluence-weighted electron mass stopping power of the medium to that of the gas.
