Röntgen

Measurement units: radiation exposure
Symbol: R

1 R = 2.58 × 10^-4 C/kg

The roentgen or röntgen is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air (statcoulomb per kilogram).
