[Approximate methods for calculating the probability of radiation complications. The PKLQ method].

A method of approximate calculation of the probability of resorption of a lesion focus by means of three mathematical models: the Poisson model, the Klepper model, and the LQ-model (the PKLQ method) is described. The method is based on a procedure for reducing SOD to the preset scope of a lesion focus. It is suggested that radio-sensitive (RS) cells predominate in the focus of lesion; radio-resistant cells are available in small quantities or their radiobiological properties differ from RS cells.
