title: Repair in normal tissues and the possible relevance to radiotherapy.
abstract: Between each fraction in radiotherapy, there is repair and recovery of both normal and neoplastic tissues. Several different types of repair have been identified. Some relate specifically to the effect of changing the number of fractions and others to the overall treatment time. Each will be discussed and particular attention will be paid to slow repair phenomena which have recently been the subject of much interest.
