What Is This Tool?
This unit converter translates radiation dose rate values from picogray per second (pGy/s), an ultra-low dose measurement, to megagray per second (MGy/s), which represents extremely high dose rates. It facilitates understanding and comparing radiation levels across vastly different scales.

Limitations
-
The large scale difference (10^-18) requires careful consideration of measurement accuracy
-

-
Megagray/second applies exclusively to extremely high-intensity radiation scenarios
-
Direct comparisons may not reflect practical measurement capabilities across scales
Frequently Asked Questions
-
What does picogray per second measure?
-
Picogray per second quantifies very low absorbed radiation dose rates in materials, representing the energy deposited at the scale of 10⁻¹² gray per second.
-
When is megagray per second used?
-
Megagray per second is used to express extremely high radiation dose rates, such as in high-energy physics experiments or testing radiation hardness of electronics.
-
Why is the conversion factor so small between pGy/s and MGy/s?
-
Because one picogray per second equals 10⁻¹² gray/second and one megagray per second equals 10⁶ gray/second, the conversion involves a factor of 10⁻¹⁸, reflecting a vast difference in scale.
Key Terminology
-
Picogray/second (pGy/s)

-
Megagray/second (MGy/s)
-
An SI-derived unit of absorbed dose rate equal to 10⁶ grays per second, used for expressing extremely high radiation dose rates.
-
Absorbed Dose Rate
-
