TIL that the CUORE Detector located under Gran Sasso uses lead from a Roman shipwreck in its experiments as radioactive-free shielding in its hunt for neutrinos User closetsquirrel, in the Today I Learned (TIL) subreddit, 30 Jul 2022
TIL: Lead from Roman shipwrecks was used in neutrino detection experiments because it sat underwater for 2,000 years. User wheatfieldcrows, in the Today I Learned (TIL) subreddit, 21 Dec 2015
TIL that physicists used 2000 year old Roman lead ingots to shield a particle detector because the lead had almost completely lost its natural radioactivity. This would keep background radioactivity in measurements to a minimum. User the_tonsil_tickler, in the Today I Learned (TIL) subreddit, 26 Feb 2014
