Frequently Asked Questions
How many Coulombs per kilogram are in 1 Roentgen?
Exactly 0.000258 C/kg (2.58 × 10⁻⁴ C/kg). Inversely, 1 Coulomb per kilogram equals approximately 3,876 Roentgens (1 C/kg = 3,875.97 R).
What is the difference between Radiation Exposure and Absorbed Dose?
Radiation exposure (measured in Roentgens or C/kg) measures the total ionization charge produced in a volume of dry air by photons. Absorbed dose (measured in Grays or rads) measures the physical energy deposited in any material or tissue mass (1 Gy = 1 J/kg).
Why is the Roentgen restricted to photons in air?
By international radiological definition, the Roentgen applies strictly to X-rays and gamma rays ionizing dry air. It is not defined for particulate radiation (such as alpha, beta, or neutron particles) or for non-air absorbing materials.
