Radiation that can produce ions when it interacts with matter is called ionizing radiation. Ions are the charged particles that are produced when electrons are removed from their positions in the atoms. Alpha particles, beta particles, x-rays and gamma rays are forms of ionizing radiation.
Sound, another form of energy, is not part of this spectrum. Electromagnetic radiation is different from sound in that it can travel in space and does not need a medium like air or water to travel through. Electromagnetic radiation is made when an atom absorbs energy.
