title: Dual radiation action and the initial slope of survival curves.
abstract: The concepts and tools of the Theory of Dual Radiation Action (e.g., proximity functions and gamma distributions) are outlined, and their connection to single-event cell inactivation is exemplified by an analysis and interpretation of the cross-section data obtained by Todd. It is shown that the biological effect of individual charged particles is dominated by the combined action of a few delta rays.
