Définition
- The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv). One sievert is the dose equivalent of radiation exposure imparted by ionizing X-RAY (roentgen rays) or other radiation undergoing an energy loss of 1 joule per kilogram of body tissue (l gray). One sievert is equivalent to 100 rem (roentgen equivalent in man). One gray is equivalent to the radiation exposure that deposits one joule per kilogram of animal tissue or other material, or 100 rads.
