What Is This Tool?
This converter helps translate values from the millirad (mrd), a legacy unit for absorbed radiation dose, into dekagray (daGy), a metric multiple of the gray used for higher radiation dosage measurements. It is designed for users needing precise unit conversions in medical, industrial, and environmental radiation contexts.
How to Use This Tool?
-
Enter the numerical value in millirad (mrd) you wish to convert.
-
Select millirad (mrd) as the input unit and dekagray (daGy) as the output unit.
-
Press the convert button to see the value expressed in dekagray (daGy).
Key Features
-
Converts from millirad (mrd) to dekagray (daGy) units accurately
-
Supports legacy and modern radiation dose unit translation
-
Ideal for dosimetry, radiotherapy, and radiation protection use
-
Browser-based and easy to use with straightforward inputs
-
Quickly processes small legacy units into larger SI multiples
Examples
-
Convert 500 millirad to dekagray: 500 mrd equals 0.0005 daGy.
-
Convert 1,000,000 millirad to dekagray: 1,000,000 mrd equals 1 daGy.
Common Use Cases
-
Comparing small diagnostic X-ray doses and historical radiation values using millirad.
-
Planning and reporting radiotherapy treatment doses expressed in dekagray.
-
Monitoring environmental and occupational radiation exposure at low and high dose levels.
-
Calibrating devices and dosimeters that use rad and gray units for dose measurements.
-
Describing industrial irradiation processes requiring doses in tens of grays.
Tips & Best Practices
-
Use this conversion for communicating radiation doses clearly between legacy and SI units.
-
Double-check your input units to ensure accurate conversions, especially with small or large values.
-
Be mindful that millirad is a legacy unit and may lack precision for some purposes.
-
Use dekagray units mainly for higher dose calculations to maintain practical readability.
Limitations
-
Millirad is not an SI unit and may introduce precision issues when converting across large scale differences.
-
Dekagray is suited for high dose measurements and may be impractical for very low dose values found in some diagnostics.
-
Beware of potential confusion when mixing legacy and modern measurement units.
Frequently Asked Questions
-
What does a millirad measure?
-
Millirad measures the absorbed dose of ionizing radiation, representing one thousandth of a rad, used historically in radiation dose reporting.
-
What is a dekagray used for?
-
Dekagray is a unit equal to ten grays, typically used to express higher doses in radiotherapy, radiation protection, and industrial irradiation.
-
How do I convert millirad to dekagray?
-
You multiply the millirad value by 0.000001 to get the equivalent dekagray value.
Key Terminology
-
Millirad (mrd)
-
A legacy unit of absorbed radiation dose equal to one thousandth of a rad, representing small radiation energy deposition.
-
Dekagray (daGy)
-
A metric multiple of the gray unit used for absorbed radiation dose, where 1 daGy equals 10 grays.
-
Gray (Gy)
-
The SI derived unit of absorbed radiation dose equal to one joule of radiation energy absorbed per kilogram of matter.
-
Absorbed dose
-
The amount of energy deposited by ionizing radiation per unit mass of material.
