[Dosimetric characteristics and radiobiological model of the irradiation of malignant tumors through a grid].
The concepts of a "dose gradient" and a "focal dose" were considered. It was found inappropriate to regard in grid irradiation of the whole tumor a dose absorbed in tumor open parts as a focal dose. Open field and grid irradiation methods were correlated by the criterion of cancer cell survival. At the present stage of research it is difficult to prefer one of these methods because the problems of irradiation optimization have not yet been solved for either of them.
