You won't pick up alpha particles with Geiger counter. Plutonium, which is the main concern in this case, is an alpha emitter, so it will very difficult to pick up with a Geiger. You may pick up its decay products, which emit beta and gamma radiation. According to the EPA chart [0] there is a little spike in gamma. Now whether this represent an immediate danger to the public is open to discussion, as the levels seem to be pretty low.
