Positrons are the same in the sense that they don't penetrate far into the skin, but when they collide with a particle in your body, gamma rays are generated by matter-antimatter annihilation. And gamma rays are very bad for you, indeed, as they have both high energy and can easily pass through your tissues.
The minimum photonic energy required to create an electron-positron pair is 1.022 MeV. This energy is the equivalent of the rest masses of the pair of particles created.There is a bit more to this, as conservation of momentum must be observed.he answer is a little more complex than that, so let's look. We see both a positron and an electron produced in an event we call pair production. The minimum energy required to produce the electron-positron pair would double that required to create the positron alone, or 1.022MeV (2 x 0.511 MeV).
