Two NaI(Tl) crystals of 12.5 kg each, grown by Alpha Spectra from a powder having a potassium level under the limit of our analytical techniques, form the ANAIS-25 set-up. The background contributions are being carefully studied and preliminary results are presented: their natural potassium content in the bulk has been quantified, as well as the uranium and thorium radioactive chains presence in the bulk through the discrimination of the corresponding alpha events by PSA, and due to the fast commissioning, the contribution from cosmogenic activated isotopes is clearly identified and their decay observed along the first months of data taking. Following the procedures established with ANAIS-0 and previous prototypes, bulk NaI(Tl) scintillation events selection and light collection efficiency have been also studied in ANAIS-25. 000071209 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/CPAN-CSD2007-00042$$9info:eu-repo/grantAgreement/ES/MICINN/FPI-CSD2009-00064$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-23749 000071209 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000071209 590__ $$a1.216$$b2014 000071209 591__ $$aNUCLEAR SCIENCE & TECHNOLOGY$$b9 / 34 = 0.265$$c2014$$dQ2$$eT1 000071209 591__ $$aSPECTROSCOPY$$b29 / 44 = 0.659$$c2014$$dQ3$$eT2 000071209 591__ $$aINSTRUMENTS & INSTRUMENTATION$$b31 / 56 = 0.554$$c2014$$dQ3$$eT2 000071209 591__ $$aPHYSICS, PARTICLES & FIELDS$$b22 / 27 = 0.815$$c2014$$dQ4$$eT3 000071209 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000071209 700__ $$0(orcid)0000-0002-6948-5101$$aCebrián, S.$$uUniversidad de Zaragoza 000071209 700__ $$aCuesta, C. 000071209 700__ $$aGarcía, E. 000071209 700__ $$0(orcid)0000-0002-4643-2138$$aGinestra, C. 000071209 700__ $$0(orcid)0000-0002-9043-4691$$aMartínez, M.$$uUniversidad de Zaragoza 000071209 700__ $$aOliván, M.A. 000071209 700__ $$aOrtigoza, Y. 000071209 700__ $$0(orcid)0000-0001-8278-6032$$aOrtiz de Solórzano, A.$$uUniversidad de Zaragoza 000071209 700__ $$aPobes, C. 000071209 700__ $$0(orcid)0000-0001-8732-8196$$aPuimedón, J.$$uUniversidad de Zaragoza 000071209 700__ $$aSarsa, M.L. 000071209 700__ $$aVillar, J.A. 000071209 700__ $$aVillar, P. 000071209 7102_ $$12004$$2X$$aUniversidad de Zaragoza$$bDpto.
