For 10 points, name this quantity that gives the energy per unit mass deposited by radiation.
A value closely related to this one but accounting for indirect effects is known as the kerma. The F-factor gives the proportionality between the exposure and this parameter. Multiplying this quantity by the appropriate RBE produces another closely related quantity known as the weighted or effective form of this, which gives a better measure of risk. This quantity has the SI unit Gray, whereas its effective form has the SI unit Sievert, but the respective cgs units or rad and rem are still used as well. For 10 points, name this quantity that gives the energy per unit mass deposited by radiation.
