What Is This Tool?
This converter transforms absorbed dose measurements from dekagray (daGy), a modern SI multiple of the gray, into millirad (mrd), a legacy unit used for lower-level radiation doses. It supports tasks such as radiotherapy planning, environmental monitoring, and instrument calibration.
How to Use This Tool?
-
Enter the radiation dose value expressed in dekagray (daGy).
-
Select dekagray as the source unit and millirad as the target unit.
-
Click the convert button to get the equivalent absorbed dose in millirad.
-
Review the results for use in medical dosimetry, radiation monitoring, or calibration purposes.
Key Features
-
Supports conversion between dekagray and millirad units for absorbed radiation dose.
-
Based on precise conversion rate: 1 daGy equals 1,000,000 mrd.
-
Suitable for translating high-level doses into legacy units for comparison and calibration.
-
Useful for radiotherapy totals, radiation protection, and dosimeter specifications.
Examples
-
2 daGy equals 2,000,000 mrd.
-
0.5 daGy equals 500,000 mrd.
Common Use Cases
-
Converting radiotherapy treatment doses measured in dekagray to compare with historic rad-based units.
-
Assessing environmental and occupational low-level radiation exposure using legacy units.
-
Calibrating survey meters and dosimeters that rely on rad or millirad measurements.
Tips & Best Practices
-
Use this converter to match modern absorbed dose values to legacy unit frameworks when needed.
-
Verify the context of dose units before conversion, especially in high-precision scientific work.
-
Apply conversions primarily when dealing with historical data comparison or instrument calibration.
Limitations
-
Millirad is a legacy unit and has limited relevance in current scientific dosimetry.
-
Large values result when converting from dekagray to millirad, which can be cumbersome to interpret.
-
High-precision dose measurements generally use gray and its multiples instead of millirad.
Frequently Asked Questions
-
What is the main difference between dekagray and millirad units?
-
Dekagray is a modern SI-derived unit used for high absorbed radiation doses, while millirad is a smaller, legacy unit derived from the rad, used mainly for low-level dose measurements and historic data.
Key Terminology
-
Dekagray (daGy)
-
A metric multiple of the gray equal to 10 grays, used to express high absorbed radiation doses.
-
Millirad (mrd)
-
A thousandth of a rad, a legacy CGS unit for absorbed radiation dose, representing low-level exposures.
-
Absorbed Dose
-
The amount of energy deposited by ionizing radiation per unit mass of material.
