Radioactive atoms are those atoms that do not have the correct balance of protons or neutrons. When the number of neutrons is too many or too few in relation to the number of protons, it becomes more difficult for the strong nuclear force to hold them together. The imbalance between protons and neutrons is corrected by releasing the excess neutrons or protons in the form of \u03b1-particles (nuclei of\u00a0<a href=\"https:\/\/www.experimentoscientificos.es\/en\/tabla-periodica\/helio\/\">helium<\/a>), and \u03b2 particles, which can be electrons or positrons. These 2 types of emissions give us 2 types of radioactivity:<\/p>\n<h2>TYPES OF RADIATION<\/h2>\n<ul>\n<li><strong>Radiation \u03b1<\/strong>which lightens the atomic nuclei by 4 mass units, and changes the atomic number by two units.<\/li>\n<li><strong>Radiation \u03b2<\/strong>which does not change the mass of the nucleus, and changes the atomic number by a single unit<\/li>\n<\/ul>\n<p>The <strong>Radiation \u03b3<\/strong>radiation, in turn, is due to the nucleus moving from a higher-energy excited state to a lower-energy excited state, which can remain unstable and lead to the emission of more \u03b1-, \u03b2- or \u03b3-radiation. \u03b3-radiation is therefore a very penetrating type of electromagnetic radiation, as it has a high energy per photon emitted.<\/p>\n<h2>RADIOACTIVE ELEMENTS<\/h2>\n<ul>\n<li>Polonium<\/li>\n<li>Attato<\/li>\n<li>Radon<\/li>\n<li>Fran\u00e7ois<\/li>\n<li>Radio<\/li>\n<li>Actinio<\/li>\n<li>Thorium<\/li>\n<li>Protoactinium<\/li>\n<li><a href=\"https:\/\/www.experimentoscientificos.es\/en\/uranio\/\">Uranium<\/a><\/li>\n<li>Neptunio<\/li>\n<li>Plutonium<\/li>\n<li>Americio<\/li>\n<li>Lawrencio<\/li>\n<li>Curio<\/li>\n<li>Berkelio<\/li>\n<li>Californio<\/li>\n<li>Einstenio<\/li>\n<li>Fermio<\/li>\n<li>Mendelevius<\/li>\n<li>Nobelio<\/li>\n<\/ul>\n<h2>RADIOACTIVE WASTE<\/h2>\n<p>Nuclear waste, which looks like new fuel, emits alpha, beta and gamma radiation and generates heat as a result of radioactive decay. It also contains different substances that develop their radioactivity independently, which makes it difficult to treat the waste; for example, even if the main constituent is the\u00a0<a title=\"Uranium\" href=\"https:\/\/www.experimentoscientificos.es\/en\/uranio\/\">uranium<\/a>\u00a0(95% of the waste), it is the fission products of the fuel (2% of the waste) that are most active for the first 150-200 years. These wastes also include plutonium-240, which has a half-life of approximately 6,600 years; and neptunium-237, with a half-life of 2,130,000 years.<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>WHAT IS RADIOACTIVITY Radioactivity is a property of atoms.
