Radioactive isotope table "lists ALL radioactive nuclei with a half-life greater than 1000 years", incorporated in the list above. The NUBASE2020 evaluation of nuclear physics properties F.G. Kondev et al. 2021 Chinese Phys. C 45 030001. The PDF of this article lists the half-lives of all known radioactives nuclides.
The mass of the nuclide (in daltons) is A (m n − E / k) where E is the energy, m n is 1.008664916 Da and k = 931.49410242 the conversion factor between MeV and daltons. half-life column The main column shows times in seconds (31,556,926 seconds = 1 tropical year ); a second column showing half-life in more usual units (year, day) is also ...
A medical isotope is an isotope used in medicine. The first uses of isotopes in medicine were in radiopharmaceuticals , and this is still the most common use. However more recently, separated stable isotopes have come into use.
Pages in category "Lists of isotopes by element" The following 122 pages are in this category, out of 122 total. This list may not reflect recent changes. A.
The tables of elements are sorted in order of decreasing number of nuclides associated with each element. (For a list sorted entirely in terms of half-lives of nuclides, with mixing of elements, see List of nuclides.) Stable and unstable (marked decays) nuclides are given, with symbols for unstable (radioactive) nuclides in italics. Note that ...
Note that medical isotopes may be not radioactive, for example deuterium (2 H) in deuterated drug. Pages in category "Medical isotopes" The following 34 pages are in this category, out of 34 total.
7 elements have 6 stable isotopes apiece; 11 elements have 5 stable isotopes apiece; 9 elements have 4 stable isotopes apiece; 5 elements have 3 stable isotopes apiece; 16 elements have 2 stable isotopes apiece; 26 elements have 1 single stable isotope. These last 26 are thus called monoisotopic elements. [3] The mean number of stable isotopes ...
