What Is This Tool?
This converter changes absorbed radiation dose measurements from decigray, an SI-derived unit, to rad, a legacy unit. It's designed to help interpret older data, support radiation protection, and facilitate material testing that still uses non-SI units.
How to Use This Tool?
-
Enter the absorbed dose value in decigray (dGy).
-
Select the target unit as rad (rd).
-
Click convert to get the equivalent absorbed dose in rad units.
Key Features
-
Simple conversion between decigray and rad units for absorbed radiation dose.
-
Supports use in medical radiotherapy, radiation protection, and materials testing.
-
Provides quick interpretation of legacy radiation dose records and non-SI unit data.
Examples
-
5 dGy equals 50 rd (5 × 10 = 50).
-
0.2 dGy equals 2 rd (0.2 × 10 = 2).
Common Use Cases
-
Interpreting legacy medical dosimetry and radiation therapy records.
-
Supporting radiation protection monitoring where non-SI units persist.
-
Characterizing radiation effects in electronics and materials testing.
Tips & Best Practices
-
Use this tool to convert dose values primarily for legacy data understanding.
-
Prefer gray-based units for clinical and regulatory accuracy when possible.
-
Keep in mind rad is a legacy unit and may not meet modern precision standards.
Limitations
-
The rad is a legacy unit less precise than SI units like decigray.
-
Conversion assumes uniform energy deposition and ignores microdosimetric nuances.
-
Some regulations require reporting in SI units, restricting rad usage.
Frequently Asked Questions
-
Why convert decigray to rad units?
-
Converting helps interpret older medical records, perform radiation protection assessments, and analyze materials testing data that still uses rad units.
-
What is the conversion rate between decigray and rad?
-
1 decigray equals 10 rad.
-
Is the rad unit recommended for modern radiation dose measurements?
-
No, rad is a legacy unit and modern standards prefer SI units such as gray and decigray for accuracy.
Key Terminology
-
Decigray [dGy]
-
An SI-derived unit equal to one tenth of a gray, measuring absorbed ionizing radiation dose.
-
Rad [rd]
-
A legacy unit of absorbed radiation dose equal to 0.01 gray, used in older medical and radiation protection contexts.
