The SI unit of absorbed dose is what?

Explanation:
Absorbed dose is the amount of radiation energy deposited per unit mass of matter. Its SI unit is the gray, defined as one joule of energy deposited in one kilogram of material. This unit directly measures energy uptake by tissue. The other units relate to different concepts: the rad is an older unit equal to 0.01 gray; the rem is an older unit for dose equivalent that accounts for biological effect, and the sievert is the SI unit for dose equivalent. In terms of relationships, 1 gray equals 100 rad, while 1 sievert equals 100 rem. Since the question focuses on energy deposited per mass, gray is the correct unit.
