Submission + - 2K year old shipwreck to detect double-beta decay (discovery.com)

dotancohen writes: The Cryogenic Underground Observatory for Rare Events is looking for neutrinoless double-beta decay. However, even the minute amount of radioactivity in the lead used to shield the experiment is enough to introduce error into the experiments. That's why a 2000 year old shipwreck's lead cargo is so valuable to CUORE that they financed the vessel's salvage. With all the radioactive isotope lead-210 depleted, the ancient lead may provide both adequate shielding from external radiation and not introduce it's own.
