Gamma rays are electromagnetic radiation, like X-rays. The other two types of natural radioactivity are alpha and beta radiation, which are in the form of particles. Gamma rays are the most energetic form of electromagnetic radiation, with a very short wavelength of less than one-tenth of a nanometer. Gamma radiation is the product of radioactive atoms.
The radiation one typically encounters is one of four types: alpha radiation, beta radiation, gamma radiation, and x radiation. Neutron radiation is also encountered in nuclear power plants and high-altitude flight and emitted from some industrial radioactive sources. Gamma radiation and x rays are highly penetrating electromagnetic radiation. 2  Some characteristics of these radiations are: 3  Examples of some gamma emitters: iodine-131, cesium-137, cobalt-60, radium-226, and technetium-99m. 4  Gamma radiation or x rays are able to travel many feet in air and many inches in human tissue.
