| gamma rays |
Electromagnetic rays similar to X-rays, emitted in an unstable atom's nucleus, which travel in straight paths at the speed of light, penetrate matter readily, but do not make the material radioactive. They penetrate a greater area than alpha or beta rays, but do less damage because they are weaker form of radiation.
