Document Summary
Radiation is energy in transit in packet behaving either as particles or as waves one first of radiation is the radioactive decay other items of certain chemical elements such as uranium. Many atoms are undergoing the radioactive decay admits steady stream of such particles that is radiation. The particles ejected from the nucleus of an atom doing radioactive decay can be either alpha particles are beta particles. An alpha particle consist of two protons plus two neutrons. A beta particle is an electron and with the ejection of this negative particle from the nucleus a neutron is converted to a proton. The ejection of either alpha or beta particles changes the number of protons in the nucleus and this changes the chemical element. Decays occur in chains creating new elements in characteristic series. Ionizing and non-ionizing radiation: functional distinctions based on radiation biological effects.
