What Is This Tool?
This converter allows you to change measurements of radiation exposure from millicoulomb per kilogram (mC/kg) to microcoulomb per kilogram (µC/kg). Both units quantify the electric charge generated by ionizing radiation in air, useful for dosimetry, calibration, and radiation protection monitoring.
How to Use This Tool?
-
Enter the value in millicoulomb per kilogram (mC/kg) you want to convert
-
Select millicoulomb/kilogram as the original unit and microcoulomb/kilogram as the target unit
-
Click convert to get the equivalent value in microcoulomb per kilogram (µC/kg)
Key Features
-
Converts millicoulomb/kilogram to microcoulomb/kilogram with a fixed conversion rate
-
Supports units used in ionization chamber calibration and radiation survey measurements
-
Browser-based and easy to use for quick radiation exposure conversions
-
Suitable for medical radiology, radiotherapy, and radiation safety applications
Examples
-
2 mC/kg = 2 × 1000 = 2000 µC/kg
-
0.5 mC/kg = 0.5 × 1000 = 500 µC/kg
Common Use Cases
-
Calibrating ionization chambers and survey meters in diagnostic and therapeutic radiology
-
Reporting radiation exposure output from medical X-ray, CT, and fluoroscopy devices
-
Regulatory and workplace monitoring of ionizing radiation exposure for safety compliance
Tips & Best Practices
-
Ensure measurement is taken under standard dry air conditions for accuracy
-
Use calibrated instruments to obtain reliable radiation exposure readings
-
Apply the conversion only for exposure units, not for absorbed radiation doses in tissue
Limitations
-
Conversion applies solely to radiation exposure measured in dry air via ionization
-
Does not convert absorbed dose units or account for biological effects without adjustments
-
Accuracy depends on proper calibration and stable environmental conditions during measurement
Frequently Asked Questions
-
What does millicoulomb per kilogram measure?
-
It measures the net electric charge of ion pairs in dry air caused by ionizing radiation exposure, commonly used in dosimetry and calibration.
-
Why convert millicoulomb/kilogram to microcoulomb/kilogram?
-
To express radiation exposure with finer granularity or to meet instrumentation and reporting standards in radiation protection.
-
Can I use this conversion for absorbed radiation dose in tissue?
-
No, these units are specific to exposure in air and do not apply to absorbed dose units without additional conversion formulas.
Key Terminology
-
Millicoulomb per kilogram [mC/kg]
-
A unit of radiation exposure quantifying the net charge of ion pairs produced in dry air by ionizing radiation, defined as 10⁻³ coulombs per kilogram.
-
Microcoulomb per kilogram [µC/kg]
-
An SI-derived unit of radiation exposure representing electric charge produced in one kilogram of air by ionizing photons, equal to 1×10⁻⁶ coulombs per kilogram.
-
Radiation Exposure
-
The amount of ionization produced in air by X-rays or gamma rays, measured as electric charge per mass of air.
