The ANAIS-25 set-up at the LSC consists of two prototypes, amounting 25 kg NaI(Tl), grown from a powder having a potassium level under the limit of our analytical techniques, and installed in a convenient shielding at the LSC. The background has been carefully analyzed and main results will be summarized in this paper, focusing on the alpha contamination identified in the prototypes and the related background contributions. Status of fulfillment of ANAIS experimental goals and prospects for the building of ANAIS-250 experiment will be also revised. 000032755 536__ $$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-23749$$9info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio2010-MULTI-DARK-CSD2009-00064$$9info:eu-repo/grantAgreement/ES/MICINN/CPAN-CSD2007-00042 000032755 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000032755 592__ $$a0.262$$b2015 000032755 593__ $$aPhysics and Astronomy (miscellaneous)$$c2015 000032755 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000032755 700__ $$0(orcid)0000-0002-6948-5101$$aCebrián, S.$$uUniversidad de Zaragoza 000032755 700__ $$0(orcid)0000-0003-1190-7233$$aCuesta, C. 000032755 700__ $$0(orcid)0000-0002-9827-2332$$aGarcía, E.$$uUniversidad de Zaragoza 000032755 700__ $$0(orcid)0000-0002-4643-2138$$aGinestra, C. 000032755 700__ $$0(orcid)0000-0002-9043-4691$$aMartínez, M.$$uUniversidad de Zaragoza 000032755 700__ $$0(orcid)0000-0001-7025-061X$$aOliván, M.A.$$uUniversidad de Zaragoza 000032755 700__ $$0(orcid)0000-0002-2793-7544$$aOrtigoza, Y. 000032755 700__ $$0(orcid)0000-0001-8278-6032$$aSolórzano, A.
