the relative susceptibility of cells, tissues, organs, organisms, or other substances to the injurious action of radiation.
(1) A relative susceptibility of cells, tissues, organs, or organisms to the effects of radiation. (2) The radiation dose required to produce a defined level of cell inactivation. Usually indicated by the surviving fraction at 2 Gy ( i.e., SF2) or by the parameters of the linear-quadratic or multitarget equations.
The degree to which a type of cancer responds to radiation therapy.
How susceptible a cell, cancerous or healthy, is to radiation. Cells that divide frequently are especially radiosensitive and are more affected by radiation.
A tumor's susceptibility to growth inhibition or cell killing by radiation therapy.
Radiosensitivity is the relative susceptibility of cells, tissues, organs or organisms to the harmful effect of ionizing radiation. Cells are least sensitive when in the S phase, then the G1 phase, then G2 phase and the most sensitive in the M phase of the cell cycle.
