Compton scattering. Pair production. Gamma rays travel at the speed of light, and they can travel thousands of meters in the air before spending their energy. WebbGamma radiation and x rays are highly penetrating electromagnetic radiation. Some characteristics of these radiations are: Gamma radiation or x rays are able to travel many feet in air and many inches in human tissue. They readily penetrate most materials and are sometimes called "penetrating" radiation. X rays are like gamma rays. mixed flowers.jpg
