(See Roentgen Absorbed Dose)
Roentgen absorbed dose. a basic unit of absorbed radiation dose. It is being replaced by the ' gray,' which is equivalent to 100 rad. One rad equals the dose delivered to an object of 100 ergs of energy, per gram of material.[] [ Click "BackButton" for previous location
radiation absorbed dose. The absorption of 1/100th of a joule of ionising radiation per kilogram. A satellite in LEO receives about 1 rad per day. Commercial semiconductors fail after around 2000 rads, military parts must survive even higher doses. The transputer fails at around 10,000 rads. Humans fail after 100 to 200 rads.
"Radiation absorbed dose". A measure of the amount of radiation absorbed by tissues (100 rad = 1 Gray).
A rad is a measure of the amount of energy absorbed by the body.
Radiation absorbed dose. A unit of measurement of the absorbed dose of ionizing radiation.
A measure of radiation exposure defined in terms of the total amount of energy absorbed per unit mass of the absorbing material. One rad is equal to 100 erg of energy deposition per gram 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, e.g., 5 krad [water] per month.
A unit of radiation delivered to tissue. Means radiation absorbed dose. Has been superseded by the Gray(Gy). 100 rads = 1 Gy. 1rad = 1 cGy (centigray).
A unit of radiation, equal to one centigray. See Centigray.
Radiation Absorbed Dose (Unit of measurement of radiation absorbed by humans)
A rad is a unit used to measure the absorbed dose, or the amount of energy body tissues absorb. However, equal doses of different types of radiation may not have the same effects on the body. For instance, a dose of alpha particles is more damaging than the same dose of gamma rays or beta particles. [Back to Module 2

(Radiation Absorbed Dose) The unit for absorbed dose that quantifies the amount of energy absorbed per gram of material. The unit used in countries other than the United States is the gray (Gy). One Gy equals 100 rad.
A unit of measure of absorbed radiation. Acronym for radiation absorbed dose. One rad equals 100 ergs of radiation energy per gram of absorbing material.
(Radiation absorbed dose) A unit used to measure a quantity of absorbed radiation. A rad relates to the amount of energy actually absorbed into some material and is used to measure any type of radiation and any type of material but it does not describe the biological effects of radiation.
Short form for "radiation absorbed dose;" a measurement of the amount of radiation absorbed by tissues (100 rad = 1 Gray).
Short form for "radiation absorbed dose"; an older term of measurement of the amount of radiation absorbed by the body (1 rad = 1 cGy).
