What is a gigagray and when is it used?

A gigagray is an SI-derived unit equal to one billion grays, mainly used for describing extremely large radiation doses in scientific research, nuclear engineering, and astrophysics.

How does gray differ from gigagray?

The gray is the standard SI unit for absorbed radiation dose used in medical and industrial fields, whereas the gigagray is a larger unit for very high doses rarely encountered outside specialized fields.

Why convert gigagray values to gray?

Converting to gray helps in comparing and communicating radiation dose data using the common SI unit prevalent in dosimetry, radiotherapy, and radiation protection.
