Talk:Isotopes of lead

message: Thorium mentions that lead-212 (a daughter nuclide of Thorium) is used in nuclear medicine, citing two sources:
* 
* 
Some other possibly relevant sources:
* Lead-212 (Medical)
* Nuclear medicine - AREVA group
* Biological effect of lead-212 localized in the nucleus of mammalian cells: role of recoil energy in the radiotoxicity of internal alpha-particle emitters
* Areva seeks to put lead-212 in hospital
I don't have the time to integrate this into the article at the moment, so I'm leaving the ball here for someone to pick up. 71.41.210.146 (talk) 21:10, 1 January 2017 (UTC)

message: Hi, I work in nuclear physics and I never heard of the Pb208 decay. its one of the most stable nuclei due to its double-magic nature. can we add references for papers for this ? If you estimate the halflife (it is eneergetically possible) it would about 10^546 years. Talking about observational stable is simply nonsense  — Preceding unsigned comment added by 192.12.184.7 (talk) 20:51, 15 June 2021 (UTC)
replies: text: "Observationally stable" means that it theoretically can decay (energetically possible), but has never been observed to do so, nor would such a discovery affect the use of lead in practice. A few sources have explicitly mentioned this prediction, but all figures given are so high that it is unlikely to ever be observed. One of these sources (there are others as well), given in the main lead article, is accessible at . To my understanding, the most sensitive detection experiments could perhaps reach a half-life of 1028 or 1029 years, but this is still far shorter than predictions.

thread_title:  Can we add references ? Pb208 decay 

message: We see that 210Pb has a partial alpha half-life at the order of 109 years; according to , 211Pb and 212Pb should respectively have an alpha decay partial half-life at the order of 1011 years and 1013 years. The partial alpha half-lives of 210Pb and 212Pb are respectively 9 and 27 orders of magnitude longer than that of 210Po and 212Po despite having higher energy. I found it interesting that 210Pb and 145Pm have many aspects in common: similar alpha and beta half-lives, low beta energies, having two more neutrons than magic numbers, being the only ones to show alpha decay experimentally among nearby isotopes, many isotopes of the next elements (Sm and Bi) having alpha decays ... The most obvious distinction is that 210Pb is natural, while 145Pm is entirely synthetic.
According to the same link as above, 209Pb should have an alpha decay partial half-life at the order of 1024 years. Adding a single proton or a neutron to the doubly-magic 208Pb reduces alpha-stability but not greatly. 129.104.241.214 (talk) 20:28, 24 November 2023 (UTC)
