radioresistance

[-risis′təns]
Etymology: L, radiare + resistare, to withstand
the ability of cells, tissues, organs, organisms, chemical compounds, or any other substances to remain unchanged by radiation. Compare radiosensitivity. radioresistant, adj.

radioresistance

Radiation oncology The relative resistance of cells and tissues to irreversible damage by radiation; RR is greatest in terminally differentiated tissues–eg, bone, cartilage, muscle, peripheral nerve, and in certain tumors–eg, glioma, melanoma, renal cell carcinoma, sarcoma. Cf Radiosensitivity.

radioresistance (rā´dēōrēzis´təns),

n the relative resistance of cells, tissues, organs, or organisms to the injurious effects of ionizing radiation. See also radiosensitivity.
