Cumulative Radiation Damage and Cumulative Radiation Effect [PDF]

open access: yesActa Radiologica: Oncology, 1983
Different mathematical formulas capable of replacing CRE have been analyzed. The purpose was to develop an expression which would yield a value identical with CRE for regular treatment schedules, but would represent more clearly and more truthfully the radiation damage of tissue. This quantity has been called cumulative radiation damage (CRD). Its unit
