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.
There are also numerous meta states with the most stable being 102m Rh (0.141 MeV) with a half-life of about 3.7 years and 101m Rh (0.157 MeV) with a half-life of 4.34 days. The primary decay mode before the only stable isotope, 103 Rh, is electron capture and the primary mode after is beta emission.
Radithor, a solution of radium salts, which was claimed by its developer William J. A. Bailey to have curative properties. Industrialist Eben Byers died in 1932 from ingesting it in large quantities throughout 1927–1930. [3] [4]
Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium. [2] Radium may also be released into the environment by human activity: for example, in improperly discarded products painted with radioluminescent paint.
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.
Radithor was advertised as "A Cure for the Living Dead" as well as "Perpetual Sunshine". [6] Radithor was a chronically lethal mixture, and was responsible for the death of Eben Byers in 1932, who died of radiation-induced cancer after drinking about 1,400 bottles of Radithor. [6] [7] Bailey also invented the Radiendocrinator around 1930.
Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being inactive as the isotopes are stable).
Depending on the formula and the symmetry of the structure, there might be several isotopomers of one isotopologue. For example, ethanol has the molecular formula C 2 H 6 O. Mono-deuterated ethanol, C 2 H 5 DO or C 2 H 5 2 HO, is an isotopologue of it. The structural formulas CH 3 −CH 2 −O−D and CH 2 D−CH 2 −O−H are two isotopomers ...
