What does the unit petagray (PGy) represent?

Petagray is a unit of absorbed radiation dose equal to 10^15 grays, measuring energy deposited by ionizing radiation per kilogram.

Why use joule per centigram (J/cg) for absorbed dose?

Joule per centigram quantifies energy deposited per 0.01 gram, useful for expressing very large doses in small mass samples.

Are these units used in everyday radiation measurements?

No, these units are mainly for theoretical or extreme scenarios in astrophysics and high-energy physics, not typical everyday use.
