What is a petagray (PGy)?

A petagray is an SI-derived unit of absorbed radiation dose equal to 10^15 grays, used mainly for extremely large, theoretical radiation doses.

When should I use nanogray (nGy) units?

Nanograys are used for very small radiation doses, commonly in environmental measurements and low-level dosimetry.

Why convert from petagray to nanogray?

Converting from petagray to nanogray helps relate theoretical extreme dose scenarios to practical low-level dose measurements for environmental and instrument calibration contexts.
