The form of nuclear radiation that travels as waves is gamma radiation.

Here's why:

* Gamma radiation is a type of electromagnetic radiation, just like light, radio waves, and X-rays. It travels at the speed of light and has the highest energy level of all electromagnetic radiation.

* Alpha and beta radiation consist of particles, not waves. Alpha radiation is made up of helium nuclei, and beta radiation is made up of electrons or positrons.
