What does one attogray represent in terms of energy absorbed?

One attogray (aGy) represents an absorbed dose of 10^-18 joule per kilogram, quantifying extremely small energy deposition by ionizing radiation.

In what scenarios is the petagray unit typically used?

Petagray (PGy) is used for extremely large, often theoretical radiation doses such as modeling astrophysical events and high-energy physics simulations.

Why is converting attogray to petagray rarely applied in practice?

Because of the vast difference in magnitude between attogray and petagray values, this conversion is mostly theoretical and not common for practical measurements.
