I believe so. The way these things work is that there is a small amount of radioactive Americium in a chamber with only one outlet. That outlet points to some sort of detector. As long as that detector is exposed to radiation, the alarm doesn't go off. However smoke can absorb the radiation and stop the detector from being hit by it. If the detector is not "seeing" the radiation, the alarm goes off. At least I think that's how they work.
