Radiation-Exposure Converter

Simplify radiation exposure conversions. Convert between coulombs per kilogram (C/kg), roentgens (R), and sieverts (Sv) effortlessly.


Description: Radiation-Exposure Unit Converter

The Radiation-Exposure Unit Converter is a tool designed to facilitate the conversion between various units used to measure radiation exposure. Radiation exposure quantifies the amount of ionizing radiation absorbed by a material or tissue. This converter allows users to seamlessly switch between different units of radiation exposure, aiding in calculations and comparisons in fields such as radiation protection, medical imaging, and radiation therapy.

Units Explanation:

  1. Coulomb/kilogram [C/kg]: Radiation exposure expressed in coulombs per kilogram, where one coulomb per kilogram represents the amount of ionization produced per unit mass.
  2. Millicoulomb/kilogram [mC/kg]: Radiation exposure expressed in millicoulombs per kilogram, equal to one thousandth of a coulomb per kilogram.
  3. Microcoulomb/kilogram [µC/kg]: Radiation exposure expressed in microcoulombs per kilogram, equal to one millionth of a coulomb per kilogram.
  4. Roentgen [R]: Radiation exposure expressed in roentgens, a unit used to measure the amount of ionization produced by X-rays or gamma rays in air.
  5. Tissue Roentgen: A modified unit of roentgen that accounts for the different absorption properties of various tissues.
  6. Parker: A unit of exposure used in radiation biology, measuring the energy imparted to matter per unit mass.
  7. Rep: A unit of exposure used in radiobiology, representing the amount of radiation required to produce a specific biological response.

Formula:The relationship between exposure and absorbed dose can be described using the following formula:Exposure=Absorbed Dose×Mass Attenuation Coefficient\text{Exposure} = \text{Absorbed Dose} \times \text{Mass Attenuation Coefficient}

How to Convert:To convert between different units of radiation exposure, follow these steps:

  1. Determine the Initial and Target Units: Identify the unit you have and the unit you want to convert to.
  2. Find Conversion Factors: Use conversion factors based on the relationships between the units.
  3. Apply the Conversion Factor: Multiply or divide the value you want to convert by the appropriate conversion factor.
  4. Perform the Calculation: Apply the conversion factor to the value you want to convert to get the equivalent value in the desired unit.


  1. Conversion from Roentgen [R] to Coulomb/kilogram [C/kg]:1R=0.0093C/kg1\, \text{R} = 0.0093\, \text{C/kg}To convert 50 roentgens to coulombs per kilogram:50R×0.0093=0.465C/kg50\, \text{R} \times 0.0093 = 0.465\, \text{C/kg}

  2. Conversion from Millicoulomb/kilogram [mC/kg] to Microcoulomb/kilogram [µC/kg]:1mC/kg=1000µC/kg1\, \text{mC/kg} = 1000\, \text{µC/kg}To convert 0.2 millicoulombs per kilogram to microcoulombs per kilogram:0.2mC/kg×1000=200µC/kg0.2\, \text{mC/kg} \times 1000 = 200\, \text{µC/kg}

By following these steps and using appropriate conversion factors, radiation exposure values can be accurately converted between different units.
