The gamma is a unit of magnetic field strength, equal to Gauss.

One type of radioactive emission is called gamma radiation, and the Greek letter gamma () is used to denote a number of important quantities in physics, including the heat capacity ratio, intermittency factor, moment of inertia ratio, and relativistic gamma.
