low-dose radiation therapy

Pronunciation: (loh-dose RAY-dee-AY-shun THAYR-uh-pee)

Radiation treatment in which the total dose of radiation is less than that given in standard radiation therapy. In low-dose radiation therapy, the total dose may be given in fewer treatments or over a shorter period of time (fewer days or weeks) than standard radiation therapy. This may cause less damage to nearby healthy tissue.
