What Is This Tool?
This online unit converter transforms absorbed radiation doses from joule per gram (J/g), an energy per mass measurement, into millirads (mrd), a legacy radiation dose unit. It supports users in radiation physics and dosimetry by enabling translation between modern SI-based units and traditional rad-based units.

Examples
-
0.5 Joule/gram [J/g] equals 50,000,000 Millirad [mrd]
-
2 Joule/gram [J/g] equals 200,000,000 Millirad [mrd]
Common Use Cases
-
Reporting absorbed doses for small biological or material samples
-
Converting dosimetry results to legacy units for comparison
-
Calibrating radiation instruments that use rad-based units
-
Environmental and occupational exposure monitoring
-
Integrating modern SI data with historical dosimetry records
Tips & Best Practices
-
Ensure consistent use of units when comparing results
-
Use this converter to bridge SI and legacy rad-based measurements
-
Refer to examples for clarity on conversion scale
-
Be cautious when interpreting very low dose values due to large conversion factors
-
Confirm unit definitions when working with mixed measurement systems
Limitations
-
Millirad is a non-SI legacy unit that may cause confusion in mixed unit contexts
-
Large conversion factors can impact precision with low dose levels
-
Unit differences require careful comparison and understanding
Frequently Asked Questions
-
Why convert from joule per gram to millirad?
-
Converting from joule per gram to millirad helps translate absorbed dose values into traditional rad-based units, enabling comparisons with historical dosimetry data and instruments.
-
What does one joule per gram represent?
-
One joule per gram represents the energy absorbed by one gram of material due to ionizing radiation.
-
Is millirad a standard SI unit?
-
No, millirad is a legacy CGS unit and not part of the SI system, though it is still used in some radiation measurement contexts.
Key Terminology
-
Joule per gram (J/g)
-
A measure of the energy absorbed by one gram of material from ionizing radiation, used in absorbed dose quantification.
-
Millirad (mrd)
-
A legacy radiation dose unit equal to one thousandth of a rad, representing absorbed energy per unit mass.
-
Absorbed Dose
-
The amount of energy deposited by ionizing radiation per unit mass of material.
