What Is This Tool?
This converter helps transform absorbed radiation dose measurements from centigray (cGy) to rad (rd). It supports users dealing with medical physics, radiotherapy, radiation protection, nuclear medicine, and materials testing by converting between modern and legacy radiation units.
How to Use This Tool?
-
Enter the absorbed dose value in centigray (cGy) into the input field
-
Select centigray as the original unit and rad as the target unit
-
Click the convert button to display the equivalent dose in rad (rd)
Key Features
-
Converts radiation absorbed dose from centigray to rad instantly
-
Supports medical, scientific, and industrial dose measurement contexts
-
Browser-based and easy to use with no installation required
Examples
-
50 cGy equals 50 rd
-
100 cGy equals 100 rd
Common Use Cases
-
Interpreting and comparing radiation dose records where rad units are used
-
Reconciling data between modern SI units (cGy) and older references in rad
-
Calibrating and checking therapeutic radiation beams in medical physics
-
Reporting doses in radiation protection and occupational exposure contexts
Tips & Best Practices
-
Always verify which unit system (SI or legacy) is required for your application
-
Use this tool to ensure consistency when working with historical radiation data
-
Be cautious when handling regulatory or clinical data that may require SI units exclusively
Limitations
-
Rad is a legacy unit and might be less preferred than SI units in modern settings
-
This tool does not provide precision adjustments or regulatory compliance checks
-
Use caution where strict adherence to SI units like gray or centigray is required
Frequently Asked Questions
-
What is the relationship between centigray and rad?
-
One centigray (cGy) is equal to one rad (rd); both represent the same amount of absorbed radiation dose.
-
Why would I need to convert centigray to rad?
-
Conversion is often needed to interpret legacy radiotherapy records or to compare measurements between SI units and older dosing units.
-
Is rad still used in modern radiation dosing?
-
Rad is a legacy unit and less commonly used now, but it is still relevant for certain radiation protection and historical data contexts.
Key Terminology
-
Centigray (cGy)
-
A unit of absorbed ionizing radiation dose equal to one hundredth of a gray, representing energy absorbed per unit mass.
-
Rad (rd)
-
A legacy unit of absorbed radiation dose equal to 0.01 gray, used to quantify energy deposited per unit mass.
-
Gray (Gy)
-
The SI unit of absorbed radiation dose, defined as one joule of energy absorbed per kilogram of matter.
