What does 1 Gigagray represent in terms of gray units?

1 Gigagray equals one billion (10^9) gray, which measures the energy of ionizing radiation absorbed per unit mass.

When is picogray typically used?

Picogray is used to quantify extremely small absorbed radiation doses, such as in environmental monitoring or calibration of ultra-sensitive detectors.

Why is converting between Gigagray and Picogray challenging?

Because gigagray and picogray differ by a factor of 10^21, requiring careful handling to avoid numerical errors and considering instrumentation limits.
