Absorbed dose is defined as the amount of energy deposited by ionizing radiation in a substance. Absorbed dose is given the symbol D. The absorbed dose is usually measured in a unit called the gray (Gy), which is derived from the SI system. The non-SI unit rad is sometimes also used, predominantly in the USA. During radiation therapy, the cumulative absorption rates through the duration of the treatment are generally high in the area being treated. This radiation absorption may permanently destroy the glands that produce saliva, sweat, and other moisture when the dose exceeds 30 grays (Gy). The result is dry mouth and similar side effects.
