Copper bricks, which had been exposed to cosmic rays for 41 days after their casting, were used to replace the internal 10 cm of the lead shielding of a HPGe detector placed at the Canfranc Underground Laboratory. We describe the outcome of the new shielding and the cosmogenic and primordial radioisotopes observed.2016http://zaguan.unizar.es/record/5632610.1088/1742-6596/718/4/042049http://zaguan.unizar.es/record/56326oai:zaguan.unizar.es:56326info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-23749info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2014-55986-PJournal of physics.
