What is radioactivity?

What is radiation therapy? The atoms making up study atomic enactment 18 earlier stable, but some of them ar spontaneously transformed by emitting radiations which release energy. This is called radioactivity. Atoms: In nature, matter - whether water, gas, rocks, living beings - consists of molecules, which are combinations of atoms. Atoms hint a positively increase centre, around which move negatively supercharged electrons. The atom is neutral. The nucleus of the atom includes positively charged protons as well as neutrons. It is this nucleus that is transformed when a radiation is emitted by radioactivity. Protons and neutrons are, in turn, composed of quarks. Isotopes All atoms with nuclei having the same manifestation of protons form a chemic element. Having the same number of protons, they sacrifice the same number of electrons, wherefore the same chemical properties. When they aim to different numbers of neutrons, they are called isotopes. Each isotope of a prone element is designated by the entire number of its nucleons, i.e. protons plus neutrons. For instance, Uranium-238 and Uranium-235 both(prenominal) arrive 92 electrons. Their nuclei have 92 protons. Isotope 238 has 146 neutrons, and Uranium-235 has 143 neutrons. Radiations from radioactivity There are 3 types of radiations like to three types of radioactivity.

Alpha radioactivity corresponds to the procession of a atomic number 2 nucleus, a peculiarly stable structure consisting of 2 protons and two neutrons, called an a particle. Beta radioactivity corresponds to the transformation, in the nucleus: -Either of a neutron into a proton, beta- radioactivity, characterized by the sacking of an electron e- - Or of a proton into a neutron, beta+ radioactivity, characterized by the emission of an anti-electron or antielectron e+. It only appears in artificial radioactive nuclei produced by nuclear reactions. Gamma radioactivity, unlike the different two, is not related to a break of the nucleus. It...
