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 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.
Radithor, a radioactive agent consisting of triple-distilled water in which the radium isotopes 226 Ra and 228 Ra were dissolved so that it had an activity of at least one microcurie, was marketed in the United States. [96]
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. [1]
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". [10]
A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example, carbon-13 with 6 protons and 7 neutrons. The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, whereas the isotope concept (grouping all atoms of each element) emphasizes chemical over nuclear.
Of the 26 "monoisotopic" elements that have only a single stable isotope, all but one have an odd atomic number—the single exception being beryllium. In addition, no odd-numbered element has more than two stable isotopes, while every even-numbered element with stable isotopes, except for helium, beryllium, and carbon, has at least three.
This represents isotopes of the first 105 elements, except for elements 87 , 102 and 104 (rutherfordium). At least 3,300 nuclides have been experimentally characterized [1] (see List of radioactive nuclides by half-life for the nuclides with decay half-lives less than one hour).
