rad

 [rad]
acronym for radiation absorbed dose; a unit of measurement of the absorbed dose of ionizing radiation. It corresponds to an energy transfer of 100 ergs per gram of any absorbing material (including tissue). The biological effect of 1 rad of radiation varies with the type of radiation. When the dose is in rems, all types have the same biological effect.

RAD

Abbreviation for reactive airway disease.

rad

1. The unit for the dose absorbed from ionizing radiation, equivalent to 100 ergs per gram of tissue; 100 rad = 1 Gy.
2. Symbol for radian.

rad

(rad) r adiation a bsorbed d ose: a unit of measurement of the absorbed dose of ionizing radiation, corresponding to an energy transfer of 100 ergs per gram of any absorbing material.

rad

[rad]
abbreviation for radiation absorbed dose.

rad

Nuclear physics
An obsolete unit of ionising radiation (X-rays, gamma rays), which corresponds to an energy absorption of 100 ergs/g of tissue.

Vox populi-US
Slang abbreviation of radical, used popularly to describe something or someone as being exceptionally pleasing or exciting.

rad

Physics An obsolete unit of ionizing radiation–X-rays, γ rays–corresponding to an energy absorption of 100 ergs/g of tissue. Cf Gray, Roentgen.

rad

Abbreviation for radian.

rad

A unit of dosage of absorbed ionizing radiation. The rad is equal to 0.01 joule of absorbed energy per kilogram of the exposed tissue or other material.

rad

(rad)
The unit for the dose absorbed from ionizing radiation, equivalent to 100 ergs per gram of tissue; 100 rad = 1 Gy.

rad (r),

n a unit of absorbed dose of radiation: 1 r equals 100 ergs/Gm. See also rem.

rad

1. acronym for radiation absorbed dose; a superseded, non-SI unit of measurement of the absorbed dose of ionizing radiation. It corresponds to an energy transfer of 100 ergs per gram of any absorbing material (including tissue). The biological effect of 1 rad of radiation varies with the type of radiation. When the dose is in rem, all types have the same biological effect. Now replaced by the gray.
2. abbreviation for radiograph; used in medical records.
