About this conversion
Attosievert and Zeptogray are units used in the radiation family of measurements. Attosievert measures equivalent radiation dose (biological risk-weighted dose), while Zeptogray measures absorbed radiation dose (energy deposited per unit mass). This page provides the direct numeric ratio between the two units. This converter uses the precise relationship 1 Attosievert = 1000 Zeptograys (equivalently 1 Zeptogray = 0.001 Attosieverts), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
