What Is This Tool?
This converter tool changes absorbed radiation dose values from centigray to joule per milligram, helping users express energy deposited by ionizing radiation in very small masses.
How to Use This Tool?
-
Enter the absorbed dose value in centigray (cGy).
-
Select centigray as the input unit and joule per milligram as the output unit.
-
Click the convert button to see the equivalent dose in joule per milligram (J/mg).
Key Features
-
Converts radiation dose units from centigray to joule per milligram directly.
-
Supports precise measurement for micro-scale samples in radiobiology and materials testing.
-
Offers a browser-based tool for quick and simple unit conversions.
-
Includes examples demonstrating typical dose equivalences.
Examples
-
100 cGy equals 1e-6 J/mg.
-
250 cGy equals 2.5e-6 J/mg.
Common Use Cases
-
Prescribing and documenting doses in external beam radiotherapy.
-
Reporting absorbed doses in brachytherapy and nuclear medicine treatments.
-
Describing energy deposition in milligram-scale lab samples for radiobiology experiments.
-
Calculating doses for sterilization and materials testing where small sample masses are involved.
-
Calibrating therapeutic radiation beams and verifying dosimeter readings.
Tips & Best Practices
-
Ensure accurate measurement of sample mass at the milligram scale for reliable results.
-
Use this conversion primarily for micro-scale samples to avoid misinterpretation of large dose values.
-
Confirm sample composition consistency to maintain dose calculation accuracy.
Limitations
-
The joule per milligram unit signifies extremely high dose values compared to centigray; improper use outside micro-scale samples may cause confusion.
-
Requires precise mass measurement and uniform sample composition for valid dose conversion.
Frequently Asked Questions
-
What does 1 centigray represent in terms of absorbed radiation?
-
One centigray equals one hundredth of a gray, representing the energy absorbed per kilogram of material by ionizing radiation.
-
Why convert centigray to joule per milligram?
-
Converting to joule per milligram expresses absorbed energy for very small samples where dose per milligram is more practical for analysis and comparison.
-
Can this conversion be used for large samples?
-
No, due to the large dose magnitude in joule per milligram, the conversion is best suited for micro-scale samples to avoid misinterpretation.
Key Terminology
-
Centigray [cGy]
-
A unit of absorbed ionizing radiation dose equal to one hundredth of a gray, indicating energy deposited per kilogram of material.
-
Joule per milligram [J/mg]
-
A derived unit measuring energy absorbed by one milligram of material, useful for very small sample dose quantification.
-
Gray [Gy]
-
The SI unit of absorbed radiation dose, defined as one joule of energy deposited per kilogram of matter.
