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) 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 acronym for radiation absorbed dose; a superseded, non-SI unit of measurement of the absorbed dose of ionizing radiation.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.

Once blood and ultrafiltrate are shunted to the RAD cartridge and the patient is stable, reabsorption of ultrafiltrate back into the patient's blood is begun.
In the Phase I protocol, RAD therapy continued for 24 hours if the circuits remained patent.
The pH of the ultrafiltrate is measured every 4 hours to assess the function of the tubule cells of the RAD since the tubule cells adjust the pH of the ultrafiltrate by producing more or less ammonia.
The RAD technologies to be incorporated into the chips are:
This is vitally important for service providers as well as their enterprise customers," explains Amir Karo, Associate Vice President of Marketing at RAD Data Communications.
The circuit emulation core that RAD will develop for Dallas Semiconductor will fully comply with all the TDM-over-pseudowire standards of the ITU-T, IETF, MEF, and MFA Forum.
The RAD products were supplied and integrated by C.
Other UC Berkeley professors in electrical engineering and computer sciences co-founding the RAD Lab are Michael Jordan, Randy Katz, Scott Shenker and Ion Stoica.
RAD Lab researchers will focus on developing alternatives to traditional software engineering, which follows a "waterfall" model of development.
Google, Microsoft and Sun Microsystems are considered foundation members of the RAD Lab, each donating to it an average of $500,000 per year.
Due to their popularity, we have decided to broaden our Brain Teaser contests by offering the public at large a chance to submit their own riddles," states Zohar Zisapel, founder and Chairman of RAD Data Communications.
