Definition of nuclear decay

Nuclear decay is a process in which an atomic nucleus emits a certain particle and becomes another nucleus. One of the important ways to know the nucleus. When French scientist A. H. Becquerel studied the fluorescence of uranium-bearing minerals in 1896, he accidentally discovered that uranium salts can emit invisible rays with strong penetrating power that can make the photographic film sensitive. This is the rays produced by decay. In addition to naturally occurring radionuclides, there are a large number of other radionuclides that are artificially manufactured. The types of radioactivity include not only alpha, beta, and gamma particles, but also particles such as positrons, protons, neutrons, and neutrinos, as well as spontaneous fission and beta delayed particles.
