What Is This Tool?
This converter helps translate radiation dose rates from sievert per second (Sv/s), which represents biological equivalent dose rates, into milligray per second (mGy/s), a unit quantifying absorbed radiation dose rate. It supports professionals in radiation protection, medical therapy, and emergency response by linking biological and physical dose assessments.
How to Use This Tool?

Tips & Best Practices
-
Always consider the biological weighting factors when interpreting sievert-based measurements
-
Use conversions to compare effective dose rates to absorbed energy dose rates carefully
-
Apply the tool for instrument calibration and dose management in clinical settings
-
Be aware of the radiation type and energy, as they impact dose relationships
Limitations
-
Sievert measures biological effect whereas milligray measures physical absorbed dose; they are not directly equivalent in biological damage
-
Radiation type and energy differences affect the accuracy of conversions
-
Context about radiation quality and biological impact is necessary for valid dose interpretation
Frequently Asked Questions
-
What does sievert per second (Sv/s) measure?
-
It measures the rate of biologically weighted radiation dose accumulation per second, indicating how quickly a stochastic-equivalent dose is delivered to tissues.
-
Why convert sievert/second to milligray/second?
-
To relate the biologically weighted dose rate to the absorbed physical radiation dose rate, which is important for instrument calibration and radiation management.
-
Can milligray/second and sievert/second values be used interchangeably?
-
No, because sievert accounts for biological effects while milligray measures physical dose; they represent different aspects of radiation exposure.
Key Terminology
-
Sievert per second (Sv/s)
-
A unit expressing the rate of biologically weighted radiation dose accumulated per second, used for dose rate and radiation risk assessment.
-
Milligray per second (mGy/s)
-
A unit measuring absorbed radiation dose rate, equal to 10^-3 gray deposited per second, showing how quickly radiation energy is absorbed.
-
Gray (Gy)
-
The SI unit of absorbed radiation dose, where 1 Gy equals 1 joule of radiation energy deposited per kilogram of matter.
