What Is This Tool?

This converter lets you easily change measurements of radiation absorbed dose from gray (Gy), the SI unit for absorbed dose, to millirad (mrd), a legacy unit useful for low-level dose comparisons and historical data.

How to Use This Tool?

  • Enter the radiation dose value in gray (Gy) in the input field.
  • Select 'gray [Gy]' as the source unit and 'millirad [mrd]' as the target unit.
  • Click the convert button to view the equivalent dose in millirad.
  • Use the results for reporting, calibration, or dose comparison purposes.

Key Features

  • Converts radiation absorbed dose units from gray to millirad accurately according to standard conversion rate.
  • Supports practical dose comparisons by bridging SI and legacy rad-based units.
  • Useful for medical, environmental, and industrial radiation measurements.
  • Browser-based and simple to use with no specialized software required.

Examples

  • 0.5 Gray converts to 50,000 Millirad.
  • 2 Gray converts to 200,000 Millirad.

Common Use Cases

  • Prescribing and documenting radiation doses in radiotherapy treatments.
  • Calibrating radiation detectors and dosimeters used in medical and industrial settings.
  • Monitoring environmental and occupational radiation exposure at low levels.
  • Comparing historical radiation dose records with modern measurements.

Tips & Best Practices

  • Confirm unit selection before conversion to ensure accuracy.
  • Use this tool to maintain consistency when working with both modern and legacy radiation dose units.
  • Understand the context of absorbed dose measurements, especially biological effects, when interpreting results.

Limitations

  • Millirad is a legacy non-SI unit that may lack precision for advanced applications.
  • Conversion does not integrate biological effect weighting factors applied in some dose assessments.
  • Users should consider unit standardization for regulatory or clinical requirements.

Frequently Asked Questions

What is gray used for in radiation measurement?
Gray (Gy) measures the absorbed dose of ionizing radiation energy deposited per kilogram of material and is widely used in dosimetry and radiotherapy.

Why convert from gray to millirad?
Converting enables comparison with legacy rad-based units, useful for low-level dose monitoring and historical data analysis.

Is millirad an international standard unit?
No, millirad is a legacy unit from the CGS system and is not part of the modern SI units.

Key Terminology

Gray [Gy]
The SI unit of absorbed dose, representing one joule of radiation energy absorbed per kilogram of matter.
Millirad [mrd]
A legacy unit equal to one thousandth of a rad, used historically for absorbed dose measurements in low-level radiation exposure.
Absorbed Dose
The amount of energy imparted by ionizing radiation per unit mass of material or biological tissue.
