The SI unit of absorbed dose is the gray. One gray equals how many joules per kilogram?

Explanation:
Absorbed dose is a measure of how much energy is deposited in a amount of matter per unit mass. The gray is defined as the energy deposited per kilogram, so one gray equals one joule per kilogram. If you deposited 100 J in 1 kg, that would be 100 Gy, and 1 kJ in 1 kg would be 1000 Gy. Thus the correct value is 1 J/kg.
