Unit Definitions:

roentgen

R

Contextual Explanation

A traditional non-SI unit of radiation exposure. Originally defined as the quantity of X or gamma radiation that produces 1 electrostatic unit (esu) of charge per cubic centimeter of dry air at STP.

Practical Applications

Historical medical radiology records, legacy US radiation safety regulations (still occasionally seen in survey meters measuring mR/h), and historical dosimetry.

millicoulomb / kilogram

mC/kg

Contextual Explanation

Equal to 10-3 Coulomb per kilogram. A metric submultiple used for expressing moderate air ionization exposure rates.

Practical Applications

Routine calibration of medical diagnostic X-ray tubes, industrial radiography equipment verification, and QA testing for therapeutic radiation beams.

Example Calculation

To convert 1 roentgen [R] to millicoulomb/kilogram [mC/kg]:
• Conversion factor: 1 roentgen [R] = 0.258 millicoulomb/kilogram [mC/kg]
• Step: 1 × 0.258 = 0.258 millicoulomb/kilogram [mC/kg]
