About this conversion
Curie and Attogray are units used in the radiation family of measurements. Curie measures radioactive activity (the rate of radioactive decay), while Attogray 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 Curie = 3.7e+28 Attograys (equivalently 1 Attogray = 2.7027027e-29 Curies), so results stay accurate for nuclear medicine, radiation safety, health physics, and scientific research.
