About Femtocoulombs per kilogram
The femtocoulomb per kilogram (fC/kg) equals 10⁻¹⁵ C/kg. Used in computational dosimetry to characterise the ionisation yield from single low-energy photon interactions in nanogram air volumes; ultra-sensitive free-air ionisation chamber simulations in microdosimetry research report air-ionisation at the fC/kg level. 1 fC/kg = 10⁻¹⁵ C/kg = 10⁻³ pC/kg.
About Microroentgens
The microroentgen (µR) equals 2.58 × 10⁻¹⁰ C/kg. Standard unit for very low environmental gamma dose rates in legacy US instrumentation: airborne radiological surveys over background areas report µR/h; EPA environmental monitoring network stations historically logged µR/h for outdoor gamma levels. 1 µR = 2.58 × 10⁻¹⁰ C/kg.
