I know quite a bit about radioactivity thanks to my studies. I was sure all radiations could activate something, but it turns out I was wrong apparently because I can't find anything but neutron activation.

I'm pretty sure alpha, beta and gamma rays can stick to a particle, often bringing it in an unstable state that will force it to release something to get into a stable state. That's particle physics. And that's why we call them ionising radiations : because they turn atoms into ions. But my memories are definitely fuzzy, and it was not were I was the best.

Those radiations may only activate for a too short time to be useful maybe? I don't know.
