Radioactivity

@181.221.44.181:

"The radioactive isotope, Bi210, is found as a daughter product of Pb210 from Th in thorium minerals." http://www.webmineral.com/chem/Chem-Bi.shtml
"Bismuth is Not Radioactive" http://www.webmineral.com/data/Bismuth.shtml

Which minerals in this category are radioactive?--Leon II (talk) 06:59, 15 October 2020 (UTC)[reply]

@Leon II:

"Bismuth was long considered the element with the highest atomic mass that is stable, but in 2003 it was discovered to be extremely weakly radioactive: its only primordial isotope, bismuth-209, decays via alpha decay with a half-life more than a billion times the estimated age of the universe.^[1]^[2] Because of its tremendously long half-life, bismuth may still be considered stable for almost all purposes.^[2]"--181.221.44.181 (talk) 06:59, 15 October 2020 (UTC)[reply]

@181.221.44.181: This category does not contain bismuth ("extremely weakly radioactive") and its isotopes, but bismuth minerals. Which minerals in this category are radioactive?--Leon II (talk) 09:07, 20 October 2020 (UTC)[reply]

@Leon II:

Bismuth minerals are, to a lesser or greater degree, radioactive, even with extremely low radioactivity it falls into this category, as none of its isotopes are stable, and the product of its beta decay is Thallium, which in turn is stable. Bismuth is radioactive, and it cannot do not be, even though it has a "flyweight" radioactivity and a half life with almost the age of the Universe, it must be mentioned. --181.221.44.181 (talk) 18:40, 20 October 2020

Aiolosite is Not Radioactive, Aikinite is Not Radioactive, Aleksite is Not Radioactive, Aramayoite is Not Radioactive, Arcubisite is Not Radioactive, Aschamalmite is Not Radioactive, Atelestite is Not Radioactive... further the same. WP:NOR.--Leon II (talk) 08:07, 21 October 2020 (UTC)[reply]
