A bottle of Radithor at the National Museum of Nuclear Science & History in New Mexico, United States. Radithor was a patent medicine that is a well-known example of radioactive quackery. It consisted of triple-distilled water containing at a minimum 1 microcurie (37 kBq) each of the radium-226 and 228 isotopes.
Notable examples [ edit ] Tho-Radia , a cream containing radium bromide, notable for its iconic advertising using the name of Dr. Alfred Curie, who shared the surname of Pierre and Marie Curie but had no connection to them.
Byers's death received much publicity and it heightened awareness of the dangers of radioactive "cures". [8]The Federal Trade Commission issued an order against Bailey's business to "cease and desist from various representations theretofore made by them as to the therapeutic value of Radithor and from representing that the product Radithor is harmless".

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.
This template is used in the articles for superheavy elements to produce the sortable lists of isotopes. It was created to simplify formatting and standardize references. For each isotope, a row {{isotopes summary/isotope}} is to be added. The template {} is required on any pages that use this template.
Archaeological materials, such as bone, organic residues, hair, or sea shells, can serve as substrates for isotopic analysis. Carbon, nitrogen and zinc isotope ratios are used to investigate the diets of past people; these isotopic systems can be used with others, such as strontium or oxygen, to answer questions about population movements and cultural interactions, such as trade.
It contains a table of main isotopes and eventually the standard atomic weight. This template is reused in {{Infobox <element>}} as a child Infobox (|child=yes). As of Jan 2023, a 'Main isotope' is conforming MOS:MAINISOTOPE (under construction, see WP:ELEMENTS What is a "Main_isotope"?) Each isotope has its own row, with decay modes:
Such nuclides are considered to be "stable" until a decay has been observed in some fashion. For example, tellurium-123 was reported to be radioactive, but the same experimental group later retracted this report, and it presently remains observationally stable. The next group is the primordial radioactive nuclides.
