In nuclear physics, a decay product, also known as a daughter product, daughter isotope or daughter nuclide, is a nuclide resulting from the radioactive decay of a parent isotope or precursor nuclide. Nuclear physics is the field of Physics that studies the building blocks and interactions of Atomic nuclei. A nuclide (from lat nucleus is a species of Atom characterized by the constitution of its nucleus and hence by the number of Protons, the number of Radioactive decay is the process in which an unstable Atomic nucleus loses energy by emitting ionizing particles and Radiation. The daughter product may be stable or it may decay to form a daughter product of its own. The daughter of a daughter product is sometimes called a granddaughter product.
Decay products are extremely important in understanding radioactive decay and the management of radioactive waste. Radioactive wastes are Waste types containing radioactive Chemical elements that do not have a practical purpose
In practice nearly all decay products are themselves radioactive. The result of this is that most radionuclides do not have simply a decay product, but rather a decay chain, leading eventually to a stable nuclide. In Nuclear science, the decay chain refers to the Radioactive decay of different discrete radioactive decay products as a chained series of transformations For elements above lead in atomic number, this is nearly always an isotope of lead. Characteristics Lead has a dull luster and is a dense, Ductile, very soft highly See also List of elements by atomic number In Chemistry and Physics, the atomic number (also known as the proton Isotopes (Greek isos = "equal" tópos = "site place" are any of the different types of atoms ( Nuclides Lead is generally the stable point at which decay chains stop.
In many cases members of the decay chain are far more radioactive than the original nuclide. Thus, although uranium is not dangerously radioactive when pure, some pieces of naturally-occurring pitchblende are quite dangerous owing to their radium content. Radium (ˈreɪdiəm is a radioactive Chemical element which has the symbol Ra and Atomic number 88 Similarly, thorium gas mantles are very slightly radioactive when new, but become far more radioactive after only a few months of storage. Thorium (ˈθɔːriəm is a Chemical element with the symbol Th and Atomic number 90 For other uses of mantle see Mantle An incandescent gas mantle, gas mantle, or Welsbach mantle is a device for generating
Although it cannot be predicted whether any given atom of a radioactive substance will decay at any given time, the decay products of a radioactive substance are extremely predictable. Because of this, decay products are important to scientists in many fields who need to know the quantity or type of the parent product. Such studies are done to measure pollution levels (in and around nuclear facilities) and for other matters.
