The activity is measured through the alpha production rate induced in the fiducial volume by 222Rn and its alpha-emitting progeny. The specific activity is measured to be (38.1 ± 2.2 (stat.) ± 5.9 (syst.)) mBq/m3. Radon-induced electrons have also been characterized from the decay of the 214Bi daughter ions plating out on the cathode of the time projection chamber. From our studies, we conclude that radon-induced backgrounds are sufficiently low to enable a successful NEXT-100 physics program, as the projected rate contribution should not exceed 0.1 counts/yr in the neutrinoless double beta decay sample.2018http://zaguan.unizar.es/record/7585310.1007/JHEP10(2018)112http://zaguan.unizar.es/record/75853oai:zaguan.unizar.es:75853info:eu-repo/grantAgreement/ES/MINECO/SEV-2014-0398info:eu-repo/grantAgreement/ES/MINECO/FIS2014-53371-C04This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 740055-MELODICinfo:eu-repo/grantAgreement/EC/H2020/740055/EU/Molecule for low diffusion TPCs for rare event searches/MELODICThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 690575-InvisiblesPlusinfo:eu-repo/grantAgreement/EC/H2020/690575/EU/InvisiblesPlus/InvisiblesPlusThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 674896-ELUSIVESinfo:eu-repo/grantAgreement/EC/H2020/674896/EU/The Elusives Enterprise: Asymmetries of the Invisible Universe/ELUSIVESinfo:eu-repo/grantAgreement/EC/FP7/339787/EU/Towards the NEXT generation of bb0nu experimets/NEXTJournal of High Energy Physics 2018, 10 (2018), 112 [27 pp]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
