What is milligray used for?

Milligray is used to report radiation doses in medical imaging, monitor doses in fluoroscopy, and calibrate radiation detectors for protection purposes.

When should I use petagray as a unit?

Petagray is used in modeling radiation doses in extreme astrophysical events, high-energy physics experiments, or theoretical studies involving ultra-high radiation levels.

Is petagray practical for clinical dose measurement?

No, petagray is not practical for clinical or occupational dose reporting due to its extremely large magnitude and theoretical nature.
