What is a Radiation-Absorbed Dose Converter?
A radiation absorbed dose converter is a tool that converts between units of absorbed radiation dose such as gray, rad, milligray, and joule per kilogram. It is essential for radiation therapy planning, nuclear medicine, and radiation safety compliance.
How to Convert Radiation-Absorbed Dose Units
Select the absorbed dose unit you want to convert from and the target unit using the dropdown menus. Enter your value in the input field and the converter instantly calculates the equivalent dose. Most commonly used for gray-to-rad conversions in medical physics.
Radiation-Absorbed Dose Conversion Formulas
History of Radiation-Absorbed Dose Measurement
The gray is named after Louis Harold Gray, who pioneered radiation dose measurement. One gray equals one joule per kilogram. The rad (radiation absorbed dose), an older CGS unit equal to 0.01 gray, was widely used before SI adoption and remains common in the United States.
About This Radiation-Absorbed Dose Converter
This radiation absorbed dose converter supports 12 units including gray, milligray, microgray, centigray, kilogray, exagray, rad, millirad, joule/kilogram, joule/gram, joule/centigram, and joule/milligram. It covers both SI and legacy radiation units.
Frequently Asked Questions
How do I convert gray to rad?
Multiply the gray value by 100 to get rad. For example, 0.5 Gy × 100 = 50 rad.
How do I convert rad to gray?
Divide the rad value by 100 to get gray. For example, 200 rad ÷ 100 = 2 Gy.
Is gray the same as joule per kilogram?
Yes, 1 gray equals exactly 1 joule per kilogram. The gray is simply the special name for J/kg when used for ionizing radiation absorbed dose.
What is centigray used for?
Centigray (cGy) is commonly used in radiation therapy. 1 cGy = 0.01 Gy = 1 rad. A typical radiation therapy fraction delivers 150-300 cGy to the tumor.
What is the difference between absorbed dose and equivalent dose?
Absorbed dose (gray) measures energy deposited per mass. Equivalent dose (sievert) accounts for the biological effectiveness of different radiation types by applying a quality factor to the absorbed dose.
