Radiation Exposure Units

The radiation exposure units in the radiation exposure converter are coulomb/kilogram, microcoulomb/kilogram, millicoulomb/kilogram and roentgen.

The most commonly used units for radiation exposure, which measures the amount of ionization produced in air by X-rays or gamma rays, are:

Coulomb per kilogram (C/kg): This is the standard unit for exposure in the International System of Units (SI). One coulomb per kilogram is the exposure that produces one coulomb of charge in one kilogram of air.

Roentgen (R): The roentgen is a legacy unit often used in radiology and radiation protection. One roentgen is the exposure that produces one electrostatic unit of charge per cubic centimeter of air.

While the coulomb per kilogram is the standard SI unit and is used in scientific and regulatory contexts, the roentgen is still encountered in some areas, especially in older literature or in the context of specific radiation instruments.

What is Radiation Exposure?

The radiation exposure is a measure caused by ionizing radiation like X-rays or gamma rays for a certain length of time.
