Abstract
For half a century, radiobiological theory was dominated by the notion that cellular radiosensitivity to ionizing radiations could be explained solely on the basis of the physics of energy deposition1,2. The process was extended even to explanations for the variation in relative biological effectiveness (RBE) with increased linear energy transfer (LET∞ ) associated with densely-ionizing, particulate radiations3,4 In more recent years, examination of the radiation responses of the repair-deficient S/S variant of the L5178Y murine leukemic lymphoblast has demonstrated that radiobiological theories which do not incorporate metabolic modification of radiochemical damage are untenable2.
