What does petagray (PGy) measure?

Petagray (PGy) measures radiation absorbed dose equal to 10^15 grays and quantifies the energy deposited by ionizing radiation per kilogram of material at extremely high dose levels.

How is joule per gram (J/g) related to gray (Gy)?

Joule per gram expresses energy absorbed by one gram of material and is related to the gray unit by 1 J/g equaling 1000 Gy.
