What Is This Tool?
This tool converts radiation absorbed dose measurements from rad, a legacy unit, into decigray, an SI-derived unit. It helps translate historical and legacy dose data into modern units preferred in medical, occupational, and research settings.
How to Use This Tool?
-
Enter the radiation dose value in rad [rd]
-
Select rad as the source unit and decigray as the target unit
-
Click convert to obtain the equivalent value in decigray [dGy]
Key Features
-
Converts absorbed dose from rad [rd] to decigray [dGy]
-
Supports translation of legacy radiation dose measurements to SI-derived units
-
Browser-based and easy to use for clinical and scientific users
-
Provides examples to facilitate understanding of conversions
Examples
-
5 Rad [rd] converts to 0.5 Decigray [dGy]
-
10 Rad [rd] converts to 1.0 Decigray [dGy]
Common Use Cases
-
Interpreting historical radiotherapy doses and updating legacy medical records
-
Radiation protection and occupational dose reporting in non-SI contexts
-
Material science and electronics testing involving radiation exposure
-
Radiotherapy fraction dose specification and treatment planning
-
Calibration and quality assurance of therapy dosimeters
Tips & Best Practices
-
Ensure correct data sourcing when converting legacy rad units
-
Use the decigray for intermediate dose values requiring finer precision than the gray
-
Maintain consistent unit usage in clinical or scientific reports to prevent dose misinterpretation
Limitations
-
Rad is a legacy unit rarely used in modern applications and depends on accurate historical data
-
Decigray is a fractional gray unit; other units like gray or milligray may be preferred for some tasks
-
Inconsistent unit use may lead to misunderstanding of absorbed dose values
Frequently Asked Questions
-
Why convert rad to decigray?
-
Converting rad to decigray helps translate older radiation dose measurements into a modern SI-derived unit for better compatibility in clinical and research settings.
-
What does one rad equal in decigray?
-
One rad [rd] equals 0.1 decigray [dGy].
-
When should I use decigray instead of gray?
-
Decigray is useful for specifying absorbed doses needing finer granularity than gray, such as fraction doses in radiotherapy or intermediate dose reporting.
Key Terminology
-
Rad [rd]
-
A legacy unit of absorbed ionizing radiation dose equal to 0.01 gray, used historically in radiotherapy and radiation protection.
-
Decigray [dGy]
-
An SI-derived unit of absorbed radiation dose equal to one tenth of a gray, offering finer measurement granularity.
-
Gray (Gy)
-
The SI unit of absorbed radiation dose quantifying energy deposited per unit mass.
