DIFFERENCE OF THE RADIOSENSITIVITY OF THE CELL IN RELATION TO ITS GROWING PHASES

Abstract

1) Comparison of survived ratio of irradiated yeast cell was carried out in relation to its growing phases.
2) The radiosensitivity decreases gradually from lag phase to log phase until its minimum, from which it increases again towards stationary phase.
3) The sensitivity can not be made similar, eliminating the cells in division at the time of irradiation. The sensitivity is still lower in log phase than in resting phase.
