title: Reoxygenation of the RIF-1 tumor after fractionated radiotherapy.
abstract: The regrowth delay assay was used to assess hypoxic fraction in the RIF-1 tumor. Results approximating those of earlier paired survival curve data were obtained for previously untreated tumors and tumors treated with a single dose of 15 Gy. Further studies showed that after 5 daily fractions of 5 Gy, the hypoxic fraction returned to approximate pretreatment values within 24 hr.
