Evaluation of the role potentially lethal and sublethal damage recovery in RBE of densely ionizing radiation

摘要

The new data confirming the relations between RBE and recovery of cells are presented. The quanitative evaluation of the contribution of potentially lethal and sublethal damage recovery in radiosensitivity of cells of various origin after exposure to low- and high-LET ionizing radiation was carried out. The conclusion about the greater contribution of potentially lethal damage recovery in the magnitude of RBE in comparison with sublthal damage recovery was made.
