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.
