They're not radioactive, at least not in the way you're implying. The type of Photo-luminescence they use "stores" light that it's exposed to and releases it later (via quantum mechanics stuff I don't understand).
The only kind of radiation they'll give off is electromagnetic radiation (light). Well that and whatever background radiation they'll emit.
