What Is This Tool?
This online converter transforms absorbed radiation dose measurements from decigray (dGy), an SI-derived unit, into millirad (mrd), a legacy CGS unit. It supports professionals by enabling the comparison and reporting of radiation doses across different unit systems.
How to Use This Tool?
-
Enter the absorbed dose value in decigray (dGy) into the input field
-
Select decigray as the source unit and millirad as the target unit
-
Click the convert button to display the equivalent value in millirad (mrd)
-
Review the result and apply it for your dose reporting or monitoring needs
Key Features
-
Converts decigray to millirad accurately based on defined conversion rates
-
Supports use cases in radiotherapy, dosimetry calibration, and environmental monitoring
-
Browser-based and easy to use without complex setup
-
Provides practical examples for quick reference
-
Helps translate measurements between modern SI units and legacy units
Examples
-
2 dGy converts to 20,000 mrd
-
0.5 dGy converts to 5,000 mrd
Common Use Cases
-
Specifying radiotherapy dose fractions and treatment-plan increments
-
Calibration and quality assurance of therapy dosimeters and beam outputs
-
Reporting or comparing small diagnostic X-ray doses and historical dosimetry
-
Environmental and occupational radiation exposure monitoring
-
Calibrating radiation survey meters using rad-based units
Tips & Best Practices
-
Always verify units before converting to prevent mix-ups between SI and legacy units
-
Use the converter to cross-check dose values when dealing with historical data or equipment
-
Be cautious interpreting results due to potential rounding or precision differences
-
Apply this tool in contexts requiring consistent reporting across different measurement systems
Limitations
-
Millirad is a legacy unit and may cause confusion in strictly SI-based communications
-
Conversion can introduce rounding errors especially for very small or very large dose values
Frequently Asked Questions
-
What does 1 decigray represent in terms of gray?
-
One decigray (dGy) equals one tenth of a gray (0.1 Gy), measuring the energy deposited per unit mass.
-
Why use millirad instead of gray units?
-
Millirad is a legacy unit useful for comparing historical dosimetry data and calibrating instruments that use rad-based measurements.
-
How do I convert 2 decigray to millirad?
-
Multiply 2 decigray by 10,000 to get 20,000 millirad.
Key Terminology
-
Decigray (dGy)
-
An SI-derived unit of absorbed radiation dose equal to one tenth of a gray, used in radiotherapy and dose reporting.
-
Millirad (mrd)
-
One thousandth of a rad, a legacy CGS unit representing absorbed radiation dose mainly used in historical and environmental monitoring.
-
Absorbed Dose
-
The amount of energy deposited by ionizing radiation per unit mass of material.
