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.
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]
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).
When it was realized that all of these are isotopes of the same element, many of these names fell out of use, and "radium" came to refer to all isotopes, not just 226 Ra, [5] though mesothorium 1 in particular was still used for some time, with a footnote explaining that it referred to 228 Ra. [6] Some of radium-226's decay products received ...
It consisted of triple distilled water containing at a minimum 1 microcurie (37 kBq) each of the radium-226 and radium-228 isotopes. [22] Radithor was manufactured from 1918 to 1928 by the Bailey Radium Laboratories, Inc., of East Orange, New Jersey. The head of the laboratories was listed as Dr. William J. A. Bailey, not a medical doctor. [23]
This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.

Secondary radionuclides are radiogenic isotopes derived from the decay of primordial radionuclides. They have shorter half-lives than primordial radionuclides. They arise in the decay chain of the primordial isotopes thorium-232, uranium-238, and uranium-235. Examples include the natural isotopes of polonium and radium.
