for gamma radiation 1rad=1rem, but for alpha radiation 1 rad=20rem. Why is there a difference?

Alpha radiation is more damaging per unit of energy deposited in living tissue than is beta or gamma radiation. The "quality" factor of twenty used for alpha radiation is somewhat arbitray and has changed over the years. A factor of ten is used for neutrons.
