We show that the spontaneous-emission process could be altered by continuously monitoring the emitting system by means of a spherical counter of quantum efficiency , placed at a finite distance L. This surprising result is related neither to Zeno's effect nor to any cavity effect, but is of intrinsically quantum-mechanical non-local nature.
