WebGamma rays are also produced in the important process of pair annihilation, in which an electron and its antiparticle, a positron, vanish and two photons are created. The photons are emitted in opposite directions and must each carry 511 keV of energy—the rest mass energy ( see relativistic mass) of the electron and positron. Gamma rays can ... WebSpace radiation is different from the kinds of radiation we experience here on Earth, such as X-rays or gamma rays. Space radiation is comprised of atoms in which electrons have been stripped away as the atom accelerated in interstellar space to speeds approaching the speed of light - eventually, only the nucleus of the atom remains. css 額縁風 https://remaxplantation.com
