radioactivity

radioactivity show nuclei that emit radiation without any external influence and transform it into other nuclei. The conversion of the radiant core is referred to as radioactive decay, the process, the original parent nucleus transforms into a daughter nucleus (including consequential Kern). Often the decay products are radioactive and decay again in turn. By chemical and physical agents, most of the radioactivity can not be controlled.
Man differs mainly alpha decay (the nucleus emits an alpha particle, reducing its atomic number decreases by two and its mass number by four) and beta decay (the nucleus emits an electron or position, thus increasing its atomic number increased by one or decreased). When gamma radiation is the nuclear energy in the form of protons, which either leave the atom (primary rays) or to cause disturbances in the electron shell (inner transformation and secondary radiation). The radioactive operations are always associated with excessive heat (generated one gram of radium, together with their derivatives, the decay over time of 3x106 kcal). In nature, occur about 60 radioactive substances. All elements of the atomic number 83 are up radioactive.
