Why are only alpha, beta and gamma radiation often mentioned? There are other forms of radiation.

Because those are the common forms of radiation emitted in radioactive decay. So they were the first to be given names, before it was even known that only gamma rays are actually EM radiation, the others being particles.

From decay, as exchemist notes, and ionizing radiation, which means potentially dangerous.
