What is a nanogray used to measure?

Nanogray measures very small absorbed radiation doses typical in environmental and low-level dosimetry, such as ambient gamma dose rates from soil or building materials.

Why convert nanogray to milligray?

Converting nanogray to milligray helps express very small absorbed doses in larger units that are more relevant for medical diagnostics and radiation protection.

Can this conversion tool be used for equivalent dose units?

No, this tool converts absorbed dose units only. Equivalent or effective doses require different conversion methods and considerations.

Key Features

Converts radiation absorbed dose between nanogray and milligray.
Browser-based and easy to use with quick conversion results.
Suitable for environmental, medical, and radiation protection contexts.
Includes examples and explanations for practical applications.

Examples

500 nGy converts to 0.0005 mGy.
1,000,000 nGy equals 1 mGy.

Common Use Cases

Reporting very low ambient gamma dose rates in environmental monitoring.
Assessing patient radiation dose during diagnostic imaging procedures.
Calibrating radiation detection equipment for environmental and medical radiation protection.
Evaluating public exposure after radiological contamination events.

Tips & Best Practices

Ensure accuracy by entering precise nanogray values to avoid rounding errors during conversion.
Use the conversion for dose measurements related only to absorbed dose units, not equivalent or effective dose.
Apply the tool for comparing environmental dose rates with clinical dose values consistently.
Keep in mind the different contexts where each unit is commonly applied to interpret results correctly.

Limitations

Conversion involves multiplying by a very small factor, which can cause rounding or precision errors in some digital instruments.
These units measure absorbed dose and do not represent equivalent or effective radiation doses.
Additional considerations are necessary if converting to other types of radiation dose measurements.

Key Terminology

Nanogray (nGy): An SI derived unit of absorbed radiation dose equal to 10^-9 gray, used for very small absorbed doses such as environmental radiation levels.
Milligray (mGy): A unit of absorbed radiation dose equal to one thousandth of a gray, commonly used in medical diagnostics and radiation protection.
Absorbed Dose: The amount of energy deposited by ionizing radiation per unit mass of matter, measured in joules per kilogram.
