X rays, gamma rays, alpha particles, and beta particles are ionizing radiation. Ionizing radiation has a lot of energy that gives it the ability to cause changes in atomsâa process called ionization. Radio and TV signals, microwaves, and laser light are nonionizing types of radiation.adiation is energy in the form of waves (beams) or particles. Radiation waves are generally invisible, have no weight or odor, and have no positive or negative charge. Radioactive particles are also invisible, but they have weight (which is why they are called a particle) and may have a positive or negative charge.
