a: Alpha particle: nucleus of helium (2 p, 2 n) 4He22 „Alpha particles are the nuclei of helium atoms and are composed of two neutron and two protons. There speed is 10,000-20,000 miles per second. A thin sheet of paper can stop alpha particles b: Beta particle: speedy electron „ Beta particles are high speed electrons that shoot out from radioactive atoms. They have negative charge and can travel at speed of 60,000-160,000 miles per second. g : Gamma radiation: bullets of light „Gamma particles are burst into photons emitted from electrons and are included in the electromagnetic spectrum. They travel at the speed of light. Thick layers of concrete or ;ead are required to stop gamma rays.
