Gray (Gy) is the SI derived unit of absorbed dose of radiation. The gray is the absorbed dose when the energy per unit mass imparted to matter by ionizing radiation is one joule per kilogram (Gy = J/kg). The unit is named after the British scientist Louis Harold Gray (1905-1965).

A unit of measure of radioactive energy absorbed by all or part of the body. 1 Gray equals 100 rad.

A unit of absorbed radiation dose equal to 100 rads. half-life: The time in which half the atoms of a radioactive substance will have disintegrated, leaving half the original amount. Half of the residue will disintegrate in another equal period of time.

A measure of radiation exposure defined in terms of the total amount of energy absorbed per unit mass of the absorbing material. One gray is equal to 1 joule of energy deposition per kilogram of the target material. Because the amount of energy absorbed depends on the nature of the target material, the unit is often qualified to indicate the nature of the target. One gray is equal to 100 rad.

a unit of measure for the dose of radiation therapy given to a particular part of the body

a unit used to indicate an absorbed dose of ionizing radiation equal to one joule of energy imparted to one kilogram

a unit of measurement for absorbed dose. It measures the amount of energy absorbed in a material. The unit Gy can be used for any type of radiation, but it does not describe the biological effects of the different radiations. For more information, see " Primer on Radiation Measurement" at the end of this document.

The SI unit of absorbed dose, it is equivalent to one joule per kilogram.

A measurement of absorbed radiation dose; 1 Gray = 100 rads.

A unit of measure of absorbed dose of radiation, abbreviated Gy. 1Gy=100 rad. 1 Gy=1 joule absorbed energy per kilogram mass.

Unit that measures the radiation dose (Gy). International health and safety authorities have endorsed the safety of irradiation for all foods up to a dose level of 10,000 Gy (10 kGy). One gray equals one joule of energy absorbed per kilogram of food being irradiated.

The international (SI) unit of absorbed dose in which the energy deposited is equal to one Joule per kilogram (1 J/kg).

The international unit of absorbed radiation dose. One Gray (Gy) equals 100 rad.

A unit of absorbed radiation equal to the dose of one joule of energy absorbed per kilogram of matter, or 100 rad . The unit is named for the British physician L. Harold Gray (1905-1965), an authority on the use of radiation in the treatment of cancer. The abbreviation for a gray is Gy. See also: Milligray . See the entire definition of Gray

Unit of measure used by radiation oncologists to calculate the amount of radiation used in cancer treatments. HIJK

A measurement of the amount of radiation dose absorbed by the body; 1 Gray = 100 rads.

The SI (System International) unit of absorbed radiation dose.

The special name for the SI unit of absorbed dose, kerma, and specific energy imparted equal to one joule per kilogram. One gray equals one joule per kilogram. The previous unit of absorbed dose, rad, has been replaced by the gray. 1 Gy = 100 rad.

Unit of absorbed dose due to any type of radiation. An exposure to 1 gray results from radiation depositing one joule per kilogram of animal tissue or any other material.

The SI unit of absorbed dose; 1 gray = 100 rads.

Standard international unit of absorbed dose. One gray is equal to an absorbed dose of 1 joule/kilogram or 100 rads.

Modern unit of radiation dosage.

The SI unit of absorbed radiation dose, one joule per kilogram of tissue.

(Gy) is the SI unit of absorbed dose. One gray is equal to an absorbed dose of 1 Joule/kilogram (100 rads). 1 Gy = 100 rads.

the newer, international unit of measurement of radiation transfer. One gray equals 100 rads. Therefore, one rad equals one centigray (cGy). See also rad.
