No. It's not green either. Radioactivity is invisible.

There's a blueish-green glow (more blue than green) due to something called Cerenkov radiation that's sometimes associated with radioactive objects. But that's just ordinary blue(ish) light, not "radioactivity". (It's still "radiation", of course, as is all other light.)
