  Units: R
One rad is equal to a dose of 0.01 joule of energy per kilogram of mass (J/kg), or 100 ergs of energy per gram of mass.
The SI unit of radiation dose is the gray (Gy); one rad equals 0.01 gray or 1 centigray.
The unit is named for the New Zealand nuclear physicist Ernest Rutherford, later named Lord Rutherford (1871-1937), whose study of radioactivity led to the discovery in 1911 that most of the mass of an atom is concentrated in a tiny nucleus.

 Reicharbeitdienst
The company-sized RAD Abteilung - not to be confused with the unit of the same name in the Wehrmacht which was a battalion-sized unit - was the core group around which the functions of the Reichsarbeitdienst revolved.
During the summer of 1938 until the war began, 300 RAD units aided in the construction of the Westwall fortification line along the western German boarder, while in the east, another 100 RAD units aided in the construction of the Ostwall fortification line along the eastern German boarder.
RAD units served on all fronts during WWII, from Norway to the Mediterranian Sea, and from France in the west, to the far reaches of Russia in the east.

 rem   (Site not responding. Last check: 2007-11-05)
For example, a dose of 1 rad of alpha particles will do ten to twenty times as much damage as a dose of 1 rad of X rays, even though both exposures would deposit the same amount of energy in the tissue.
To describe this difference, a factor called relative biological effectiveness (RBE) is used, which is the ratio of the size in rads of a dose of X rays to the size in rads of a dose of another type of radiation causing the same amount of damage.
Rems are then defined by dose in rems = dose in rads × RBE
