About Radiation Exposure Units
Radiation exposure quantifies the ionization of air due to X-rays or gamma rays. It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air.
- Coulomb/kilogram (C/kg): The SI unit of radiation exposure.
- Millicoulomb/kilogram (mC/kg): $1 \text{ mC/kg} = 10^{-3} \text{ C/kg}$
- Microcoulomb/kilogram (µC/kg): $1 \text{ µC/kg} = 10^{-6} \text{ C/kg}$
- Roentgen (R): An older unit of exposure. $1 \text{ R} = 0.000258 \text{ C/kg}$.
- Tissue roentgen: Defined as equivalent to Roentgen for this conversion. $1 \text{ tissue roentgen} = 1 \text{ R}$.
- Parker: Defined as equivalent to Roentgen for this conversion. $1 \text{ parker} = 1 \text{ R}$.
- Roentgen equivalent physical (rep): Defined as equivalent to Roentgen for this conversion. $1 \text{ rep} = 1 \text{ R}$.
