What Is This Tool?
This online converter allows you to transform absorbed radiation dose rates from the legacy unit rad per second (rd/s, rad/s) into joule per kilogram per second (J·kg⁻¹·s⁻¹), which aligns with the modern SI unit gray per second. It supports various radiological and environmental applications by facilitating accurate unit translation.
How to Use This Tool?

Tips & Best Practices
-
Always verify the units you're converting to ensure accurate dose assessment
-
Use this tool to update legacy data into SI-compatible units for consistency
-
Double-check calibration settings of radiation monitoring instruments
-
Apply conversion carefully to avoid misinterpretation of absorbed dose rates
-
Reference this conversion in radiological reporting to align with modern standards
Limitations
-
Rad/second is a legacy non-SI unit and can cause confusion if not converted properly
-
Precision depends on proper calibration and consistent unit use
-
The conversion factor assumes uniform energy absorption, not accounting for radiation type or biological effects
Frequently Asked Questions
-
What does rad/second measure?
-
Rad/second measures the rate at which ionizing radiation energy is absorbed in matter, representing absorbed dose rate using a legacy unit.
-
Why convert rad/second to joule/kilogram/second?
-
Converting rad/second to joule/kilogram/second translates legacy dose rate values into SI units compatible with gray per second, facilitating modern radiation monitoring and assessment.
-
Is the conversion factor always the same?
-
Yes, 1 rad/second equals 0.01 joule/kilogram/second based on standardized definitions, but accurate application requires consistent calibration and unit use.
Key Terminology
-
Rad per second (rad/s)
-
A legacy unit representing the rate at which radiation energy is absorbed, where 1 rad equals 0.01 joule per kilogram.
-
Joule per kilogram per second (J·kg⁻¹·s⁻¹)
-
An SI-compatible unit quantifying absorbed radiation dose rate, equivalent to gray per second.
-
Absorbed dose rate
-
The amount of ionizing radiation energy deposited in a material per unit mass and per unit time.
