radiosensitivity

 [ra″de-o-sen″sĭ-tiv´ĭ-te]
sensitivity of the skin, tumor tissue, or other tissue to radiant energy, such as x-ray or other radiations. adj., adj radiosen´sitive.

ra·di·o·sen·si·tiv·i·ty

(rā'dē-ō-sen'si-tiv'i-tē),
The condition of being readily affected by radiant energy.

/ra·dio·sen·si·tiv·i·ty/ (ra″de-o-sen″sĭ-tiv´ĭ-te) sensitivity, as of the skin, tumor tissue, etc., to radiant energy, such as x-rays or other radiation.radiosen´sitive

radiosensitivity

[-sen′sitiv′itē]
the relative susceptibility of cells, tissues, organs, organisms, or any other substances to the effects of radiation. Cells of self-renewing tissues, such as those in the crypts of the intestine, are the most radiosensitive. Cells that divide regularly but mature between divisions, such as spermatogonia and spermatocytes, are somewhat less radiosensitive. Long-lived cells that usually do not divide unless there is a suitable stimulus, such as liver, kidney, and thyroid cells, are even less radiosensitive. Least radiosensitive are cells that have lost the ability to divide, such as neurons. Compare radioresistance. radiosensitive, adj.

radiosensitivity

The relative susceptibility of cells and tissues to irreversible damage by RT, which prevents mitosis or completion of normal metabolism; lymphoid, hematopoietic, and gonadal tissues are most susceptible to radiation damage; some CAs–eg, lymphoproliferative, gonadal malignancies–eg, seminoma and small cell carcinoma of lung 'melt away' with RT. Cf Radioresistance.
