What Is This Tool?
This tool converts radiation dose rates from rad per second, a legacy unit used to measure absorbed radiation dose rates, into exagray per second, an SI-derived unit representing extremely large absorbed dose rates. It is useful for translating dose rates in various scientific and industrial contexts.
How to Use This Tool?
-
Enter the value of radiation dose rate in rad/second (rd/s or rad/s).
-
Select the conversion to exagray/second (EGy/s).
-
Click convert to get the equivalent absorbed dose rate in exagray per second.
Key Features
-
Supports conversion between rad/second (legacy unit) and exagray/second (SI-derived unit).
-
Uses a precise conversion rate based on established radiation dose definitions.
-
Ideal for handling data in radiological surveys, astrophysics, and high-energy physics.
-
Browser-based and easy to use with straightforward input and output.
Examples
-
5 rad/second converts to 5 × 1e-20 = 5e-20 EGy/s.
-
0.1 rad/second converts to 0.1 × 1e-20 = 1e-21 EGy/s.
Common Use Cases
-
Interpreting legacy radiation dose rates in radiotherapy and industrial irradiation.
-
Modeling extremely high absorbed-dose rates in astrophysics such as near supernovae or gamma-ray bursts.
-
Simulating peak dose rates in high-energy-density physics and particle accelerator targets.
-
Calibrating radiation protection instruments that still reference older unit systems.
Tips & Best Practices
-
Verify unit selections before conversion to ensure accurate results.
-
Use this tool when dealing with legacy data or exceptionally high dose rates in scientific simulations.
-
Cross-check converted values when applying them to experimental or theoretical contexts.
Limitations
-
Rad/second is a legacy, non-SI unit being replaced by gray/second in modern usage.
-
Exagray/second represents an extremely large dose rate scale, limiting practical everyday use.
-
Conversions are mainly relevant for specialized scientific modeling rather than routine measurements.
Frequently Asked Questions
-
What does rad/second measure?
-
Rad/second measures the absorbed radiation dose rate, representing how much radiation energy is deposited in matter per second using a legacy unit.
-
Why convert rad/second to exagray/second?
-
Conversion is useful to translate legacy dose rates into an SI unit that expresses extremely large absorbed dose rates needed in advanced scientific simulations.
-
Is exagray/second commonly used in everyday radiation measurement?
-
No, exagray/second values are usually impractical for everyday measurements due to their immense scale and are mainly used in theoretical or high-energy physics contexts.
Key Terminology
-
Rad/second (rd/s, rad/s)
-
A legacy unit measuring absorbed radiation dose rate equal to one rad delivered each second, where 1 rad = 0.01 joule per kilogram of material.
-
Exagray/second (EGy/s)
-
An SI-derived unit for absorbed dose rate equal to 10^18 grays per second, representing extremely large radiation energy deposition rates.
-
Gray (Gy)
-
The SI unit of absorbed radiation dose, defined as one joule of radiation energy absorbed per kilogram of matter.
