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.
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.
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.
A trace radioisotope is a radioisotope that occurs naturally in trace amounts (i.e. extremely small). Generally speaking, trace radioisotopes have half-lives that are short in comparison with the age of the Earth, since primordial nuclides tend to occur in larger than trace amounts.
Eben Byers was a wealthy American socialite whose death in 1932 from using a radioactive quackery product called Radithor is a prominent example of a death caused by radium. Radithor contained ~1 μCi (40 kBq) of 226 Ra and 1 μCi of 228 Ra per bottle. Radithor was taken by mouth and radium, being a calcium mimic, has a very long biological ...
Radithor, a well known patent medicine or snake oil, is possibly the best 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 radium-228 isotopes.
For the persistent pain, a doctor suggested he take Radithor, a patent medicine manufactured by William J. A. Bailey. [5] Bailey was a Harvard University dropout who falsely claimed to be a doctor of medicine and had become rich from the sale of Radithor, a solution of radium in water which he claimed stimulated the endocrine system .
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.
