In contradistinction to the increased fraction of HeLa S 3 cells in S phase after irradiation by a single dose in a range of 25--200 R, cultures irradiated by a second dose at time of morphologic restitution of mitotic activity exhibited decreased fraction of cells in S phase. The interpretation is that passage from G1 to S was reduced due to disturbances in subsystems which have not been fully repaired.
