Why is radioactivity related to physics, not to chemistry, whereas
fluorescence and phosphorescence are explained as chemical reactions?
(in both cases, there's an energy emission....?)

I'd also  like to know about the used process to get to artificial
radioactivity.
 Thanx ,
U guys doing a GrEaT job =)
