Modification of the theory of dual radiation action for attenuated fields. II. Application to the analysis of soft X-ray results.

A formalism developed in the first paper in this series, based on the generalized Theory of Dual Radiation Action, is applied to survival data for cells exposed to soft X rays. It is shown that, in contrast to previous published analyses, this formalism--modified to account for the attenuation of dose across the sensitive matrix of the cell--is fully consistent with the experimental results. The reasons for previous disagreements are discussed.
