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.

Metric unit for absorbed dose.

The special name for the SI unit of absorbed dose; 1 Gy = 1 J kg−1.

unit of absorbed radiation dose; 100 rad = 1 Gy.

3/4 The SI unit of absorbed dose. One gray is equal to joule per kilogram. 1 Gy = 100 rad.

United States botanist who specialized in North American flora and who was an early supporter of Darwin's theories of evolution (1810-1888)

a newer unit that is used to quantify ABSORBED DOSE, where a RAD is the earlier unit that was used to quantify ABSORBED DOSE

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.

Equivalent to 100 rad.

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.

The gray (symbol: Gy) is the SI unit of absorbed dose.

An animal or thing of gray color, as a horse, a badger, or a kind of salmon.

matter: brain tissue is divided into two types: gray matter and white matter. Gray matter is made up of the cell bodies of nerve cells. The volume of gray matter tissue is a measure of the density of brain cells in a particular region. (for more, see article)

Body color a mixture of white with any other colored hairs; often born solid-colored or almost solid-colored and gets lighter with age as more white hairs appear.

Any colour from pure white to dark gray.

A color in which the skin is black, and the hair is a mixture of black and white.

Color of a horse made up of black and white hairs.

The color of the leaves caused by too much abrasion during sorting.

A horse color where the majority of the coat is a mixture of black and white hairs. The mane, tail and legs may be either black or gray unless white markings are present. Starting with foals of 1993, the color classifications gray and roan were combined as "roan or gray." See roan.

Gray is a rather depressing color; some mystics believe it to be the color of the aura of a prison. Some sources believe it to indicate a slow period in the dreamerâ€(tm)s life, when he or she is merely “marking time.

Any color from pure white to dark gray.

A mixture of white and black hairs.

A color produced by mixing white and black.

Gray or Grey is a coat color of horses, consisting of black skin, and a hair coat that is white, dappled, or white intermingled with hairs of other colors. Gray horses are usually born bay, chestnut, or black, then white hairs begin to appear at or shortly after birth and "gray out" the horse. Graying can occur at different rates--very quickly on one horse and very slowly on another.
