Abstract
Jejunal crypt survival after fractionated total body irradiation of C3H mice given at dose rates between 1.2 and 0.08 Gy/min was studied and the results analysed according to the linear quadratic model. Whereas .alpha. was independent of dose rate .beta. decreased with dose rate to approach zero at about 0.01 Gy/min. During the period of recovery, sublethal damage from doses given at high dose rate interact with low dose rate irradiation given immediately after, and increases its effectiveness.This publication has 7 references indexed in Scilit:
