Which term describes the absorbed dose per unit mass of tissue?

Explanation:
Absorbed dose describes the amount of energy deposited by ionizing radiation in a mass of tissue per unit mass. It is expressed in grays (Gy), which is joules per kilogram, and reflects the physical energy transfer to tissue. This quantity is distinct from equivalent dose and effective dose, which apply weighting factors to account for biological effects and tissue sensitivity, respectively. Exposure, in contrast, measures ionization in air, not energy deposited in tissue.
