Gamma Rays are Waves on the electromagnetic Spectrum that have a Wavelength of 10 or Higher and 11 down. Gamma Rays are produced in labs through the process of nuclear collision and also through the artificial Radioactivity that accompanies these interactions. The high energy nuclei needed for the collisions are accelerated by such devices such as the Cyclotron and synchrotron. There are also many uses for Gamma rays in Medicine. Gamma Rays are used in medicine to …

…that the universe should be producing such photons. Hard work by several brilliant scientists had shown that a number of different processes which were occurring in the universe would result in gamma ray emissions. These processes included cosmic ray interactions with interstellar gases, supernova explosions, and interactions of energetic electrons with magnetic fields. In the 1960's we finally developed thew ability to actually detect these emissions and we have been looking at them ever since.
