Measuring Radiation | NRC.gov
Mar 20, 2020 · Many radiation monitors measure exposure. The units for exposure are the roentgen ( R ) and coulomb/kilogram (C/kg). A bsorbed dose describes the amount of radiation absorbed by an object or person (that is, the amount of energy that radioactive sources deposit in materials through which they pass).
