> Particles emitted from radioactive atoms are a form of ionizing radiation—they have enough energy to scramble atoms and molecules they crash into. (This is different from non-ionizing radiation, like the kind emitted by your cell phone, which does not have enough energy to break bonds.)

I think this is a poor explanation. Radiation from your cell phone is electromagnetic radiation. This is far different from a radiated particle, an actual proton or electron flying out.

Essentially a particle vs a wave, which is more of a difference than "not enough energy". Is that correct?
