Peanut Gallery for the Keys/RAZD Debate

The problem with what Keys is saying is that you can't just simply make decay "faster". Aside from the fact that there is no mechanism it speaks about decay as if it were some independant phenomena rather than an effect of weak force interactions. You could make decays slower by changing particle masses, but that's a little severe (and I really don't see a mechanism to do that) or have time-dependant coupling constants or other stuff. Again however all this stuff has really noticable consequences which we don't see.
Making radiation "faster" would have very non-trivial consequences, because you'd need the modify the weak force which is fundamental for other stuff.
