  2. Radithor - Wikipedia

    en.wikipedia.org/wiki/Radithor

    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.

  3. List of radioactive nuclides by half-life - Wikipedia

    en.wikipedia.org/wiki/List_of_radioactive...

    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.

  4. Isotopes of radium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_radium

    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 ...

  5. Template:Isotopes summary - Wikipedia

    en.wikipedia.org/wiki/Template:Isotopes_summary

    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.

  6. Radioactive quackery - Wikipedia

    en.wikipedia.org/wiki/Radioactive_quackery

    These spas were world-renowned, as evidenced by an article in the New Zealand Thames Star Supplement from 1912 (the article uses the Austrian name of the town, Joachimsthal). [7] Similar spas currently exist in Germany, Ukraine, Belarus and Austria [ 8 ] [ 9 ] [ 10 ] and in Germany they are covered by public health insurance.

  7. Template:Infobox radium isotopes - Wikipedia

    en.wikipedia.org/wiki/Template:Infobox_radium...

    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:

  8. Trace radioisotope - Wikipedia

    en.wikipedia.org/wiki/Trace_radioisotope

    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.

  9. List of nuclides - Wikipedia

    en.wikipedia.org/wiki/List_of_nuclides

    A further 10 nuclides, platinum-190, samarium-147, lanthanum-138, rubidium-87, rhenium-187, lutetium-176, thorium-232, uranium-238, potassium-40, and uranium-235 have half-lives between 7.0 × 10 8 and 4.83 × 10 11 years, which means they have experienced at least 0.5% depletion since the formation of the Solar System about 4.6 × 10 9 years ...
