What is the difference between nanogray and rad?

Nanogray (nGy) is an SI-derived unit for absorbed radiation dose equal to 10^-9 gray, used for very small doses. Rad (rd) is a legacy unit equal to 0.01 gray, historically used for absorbed dose measurement.

Why convert nanogray to rad?

Conversion allows interpretation of small absorbed doses measured in SI units into legacy rad units for comparison with historical data or regulations that still reference rads.

Can this converter be used for high radiation doses?

This tool is designed for small dose values like those in nanograys; for high doses, other conversion approaches or units may be more appropriate.

Tips & Best Practices

Ensure precise calibration of instruments measuring nanogray doses before conversion
Use this converter to support interpretation of doses in contexts still referencing rads
Double-check small dose values due to potential measurement limitations
Understand that rad is a legacy unit and is less precise than gray
Apply conversion results carefully when assessing low-level environmental exposures

Limitations

The rad is a non-SI legacy unit with lower precision than gray
Converting very low doses may approach the limit of measurement accuracy
Measurement and calibration uncertainties in nanogray can affect conversion results
