RAD

Rad

The rad is a deprecated unit of absorbed radiation dose, defined as 1 rad = 0.01 Gy = 0.01 J/kg. It was originally defined in CGS units in 1953 as the dose causing 100 ergs of energy to be absorbed by one gram of matter. It has been replaced by the gray in SI but is still used in some countries. A related unit, the roentgen, is used to quantify the number of rad deposited into a target when it is exposed to radiation. The F-factor can be used to convert between rad and roentgens.
