About this radiation measurement converter
Convert exposure measurement units used by health physicists, radiation safety officers, medical imaging teams, and labs working with X-ray and gamma-ray fields in air.
These units describe ionization produced in air. They are different from absorbed dose units such as gray and equivalent dose units such as sievert.
Units covered
Roentgen scale
R, mR, and uR for traditional exposure readings and survey meter references.
SI exposure
C/kg, mC/kg, and uC/kg for standardized exposure measurements.
Air ionization
Focused on exposure from X-rays and gamma rays in air.
How to use it
- Enter the exposure measurement from a reference, detector, or procedure note.
- Choose roentgen-based or coulomb-per-kilogram units as needed.
- Use absorbed dose converters when you need energy deposition in material or tissue.
