The amount of radiation energy absorbed, especially by human tissue; measured in rads.
Energy imparted to matter in a suitably small element of volume by ionizing radiation divided by the mass of that element of volume. The SI unit for absorbed dose is joule per kilogram (J kg-1) and its special name is gray (Gy). ISO, 1972 RT ionizing radiation.
the amount of energy deposited in a unit of biological tissue. The units of absorbed dose are the rad and gray.
The amount of energy imparted by nuclear radiation to unit mass of absorbing material. The unit is the rad. See; Dose, Rad.
Absorbed dose is the amount of energy deposited in any material by ionizing radiation. It is a measure of energy absorbed per gram of material. The SI unit of absorbed dose is the gray. The special unit of absorbed dose is the rad.
the amount of energy deposited by ionizing radiation in a unit mass of tissue. It is expressed in units of joule per kilogram (J/kg), and called " gray" (Gy). For more information, see " Primer on Radiation Measurement" at the end of this document.
The energy imparted to matter by ionizing radiation per unit mass of irradiated material at the place of interest. The rad is a unit of absorbed dose.
Absorbed dose is a measure of the energy deposited by radiation in a certain material. The SI unit for absorbed dose is the gray (Gy). One gray is an absorbed radiation dose of 1 joule per kilogram. 1 Gy = 1 J/kg.
The energy imparted by ionizing radiation per unit mass of material irradiated. For purposes of radiation protection and assessing risks to human health, the quantity normally calculated is the average absorbed dose in an organ or tissue, equal to the total energy imparted to that organ or tissue divided by the total mass. The SI unit of absorbed dose is the joule per kilogram (J kg-1), and its special name is the gray (Gy). In conventional units used in this report, absorbed dose is given in rads; 1 rad = 0.01 Gy.
the amount of energy imparted to matter by ionizing radiation per unit mass of irradiated material. The unit of absorbed dose is the Rad, which is 100 ergs/gram.
The energy absorbed by matter from ionizing radiation per unit mass of irradiated material at the place of interest in that material. The absorbed dose is expressed in units of rad (or gray) (1 rad = 0.01 gray).
Absorbed dose is the amount of energy deposited in any material by ionizing radiation. The unit of absorbed dose, the rad, is a measure of energy absorbed per gram of material. The unit used in countries other than the U.S. is the gray (abbreviated, Gy). One gray equals 100 rad.
The energy imparted to a unit mass of matter by ionizing radiation. The unit of absorbed dose is the rad. One rad equals 100 ergs per gram. The amount of a substance absorbed into the body, usually per unit of time. The most common unit of dose is mg per kg body weight per day (mg/kg-day). [S. L. Brown
In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g. skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose.
The energy imparted per unit mass by ionizing radiation to matter at a specific point. The SI unit of absorbed dose is joule per kilogram (J kg-1). The special name for this unit is gray (Gy). The previously used special unit of absorbed dose, the rad, was defined to be an energy absorption of 100 ergs/gram. Therefore, 1 Gy = 100 rad.
The energy imparted by ionizing radiation per unit of mass irradiated material. The units of absorbed dose are the rad and gray (Gy).
The amount of energy given up to matter by ionizing radiation per unit mass of irradiated material. The rad and the gray (SI) are units of absorbed dose.
Quantity of energy imparted by ionising radiation to unit mass of matter such as tissue. Unit gray, symbol Gy. 1 Gy = 1 joule per kilogram.
Absorbed dose is a measure of the energy deposited in a medium by ionizing radiation. It is equal to the energy deposited per unit mass of medium, and so has the unit J/kg, which is given the special name Gray (Gy).
