General model of radiation lesion and shape of dose-effect curve. Report 1. Number of stages of lesion

The author explores the possibility of interpreting dose-effect curves within the framework of a general model that does not restrict the structure and dynamic characteristics of the lesion process. Some results were obtained that generalize the well-known inequality of Hug-Kellerer. A class of curves was singled out, which cannot be obtained in models that suggest only one route of cell inactivation.
