Absorbed dose to tissue is traditionally expressed in which units, with Gray as the SI equivalent?

Explanation:
Absorbed dose is the energy deposited in tissue per unit mass. Traditionally, this was expressed in rad, and the SI equivalent is Gray. The relationship is 1 Gy = 100 rad, so rad paired with Gray is the correct combination for absorbed dose. Other units shown relate to different quantities: Roentgen measures exposure in air, Sievert and rem are for dose equivalent (biological effect), and Becquerel is a measure of radioactive activity.
