What does one attogray represent in terms of energy deposition?

One attogray corresponds to an absorbed dose of 10^-18 joule per kilogram, indicating an extremely small amount of energy deposited by ionizing radiation in a unit mass.

Why convert attogray to millirad?

Conversion to millirad helps put extremely small absorbed dose measurements into a legacy rad-based unit for practical comparison, calibration, and interpreting experimental or occupational radiation doses.

Is the millirad a modern or legacy radiation dose unit?

The millirad is a legacy unit based on the rad, used historically in medical and occupational dosimetry and still useful for certain environmental and survey meter calibrations.

What Is This Tool?

This online converter allows users to translate radiation absorbed dose values from attogray (aGy), a unit for extremely small doses, into millirad (mrd), a legacy CGS unit used for small measurable radiation doses. The tool facilitates comparison and compatibility between highly sensitive experimental data and more commonly used dosimetry units.

How to Use This Tool?

Enter the radiation dose value measured in attogray (aGy)
Select attogray [aGy] as the source unit and millirad [mrd] as the target unit
Click the convert button to get the equivalent dose in millirad
Review the result for interpretation in relevant scientific, medical, or safety applications

Key Features

Converts radiation absorbed dose from attogray to millirad using an established conversion rate
Supports interpretation of extremely low dose measurements in practical and historical contexts
Browser-based and easy to use without additional software
Helpful for radiation physics research, medical dosimetry, and environmental monitoring

Examples

5 attogray [aGy] converts to 5 × 10⁻¹³ millirad [mrd] (5e-13 mrd)
1,000 attogray [aGy] converts to 1 × 10⁻¹⁰ millirad [mrd] (1e-10 mrd)

Common Use Cases

Reporting extremely low absorbed doses in radiation physics experiments
Calibrating highly sensitive dosimeters and detectors in microelectronics
Environmental and occupational exposure monitoring using rad-based units
Comparing modern experimental data with historical medical dosimetry records

Tips & Best Practices

Consider the vast difference in unit scale when converting between attogray and millirad
Use this conversion to interpret very small absorbed doses in terms of more commonly known legacy units
Apply the tool in radiation safety, research, and dosimeter calibration for accurate dose comparison
Be mindful of the numerical precision required due to extremely small values involved

Limitations

Attogray measures extremely low doses, while millirad applies to small but more detectable doses
Conversion results may involve very tiny numbers that exceed routine dosimetry practical detection limits
Units differ greatly in scale, demanding careful attention when interpreting converted values
