    Say your nucleus decays by emitting a beta particle or something. The beta particle shoots off in one direction, the nucleus "recoils" by moving in the opposite direction. Same as if you fire a gun; bullet goes one way, recoil pushes gun the opposite way.

    You know, because of conservation of momentum.
