An extensive material screening and selection process to assess the radioactivity of components is underway combining several techniques, including germanium ¿-ray spectrometry performed at the Canfranc Underground Laboratory; recent results of this material screening program are presented here.2016http://zaguan.unizar.es/record/5629610.1016/j.nuclphysbps.2015.10.024http://zaguan.unizar.es/record/56296oai:zaguan.unizar.es:56296info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio-2010/CSD2008-00037info:eu-repo/grantAgreement/ES/MINECO/FIS2012-37947-C04info:eu-repo/grantAgreement/ES/MINECO/FPA2009-13697-C04-04Nuclear and Particle Physics Proceedings 273-275 (2016), 2666 - 2668byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
