What does joule per milligram [J/mg] measure?

It expresses the energy absorbed per milligram of material, quantifying the absorbed radiation dose for small mass samples.

When is petagray [PGy] typically used?

Petagray is used to represent extremely large radiation doses in theoretical studies, astrophysics, and high-energy physics simulations.

Why convert from J/mg to PGy?

Converting allows translating practical small-scale absorbed dose measurements into ultra-high theoretical dose units for specialized modeling.
