To overcome this problem we study coating materials that can act as humidity barriers, in particular parylene, a polymer that can be deposited in very radiopure, thin and conformal layers. In this work, several NaI(Tl) samples coated with 2-5 µm parylene-C were tested at low temperature. Luminescence spectra under X-ray excitation are presented at several temperatures as well as the light output vs temperature at 1.5-300 K. Several thermoluminescence peaks were observed at around 60, 95 and 150 K during warm up to room temperature The mechanical resistance of the coating under thermal cycles was also investigated, and we observed a degradation of the optical appearance and the light output after cooling down to about 100 mK, which compromises the reusability of the samples. 000032200 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/FPI-CSD2009-00064 000032200 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000032200 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000032200 700__ $$0(orcid)0000-0003-1190-7233$$aCuesta, C. 000032200 700__ $$aGarcía, E. 000032200 700__ $$0(orcid)0000-0002-4643-2138$$aGinestra, C. 000032200 700__ $$aGirard, T.A. 000032200 700__ $$aDe Marcillac, P. 000032200 700__ $$0(orcid)0000-0002-9043-4691$$aMartínez, M.$$uUniversidad de Zaragoza 000032200 700__ $$aOrtigoza, Y. 000032200 700__ $$aDe Solórzano, A.O. 000032200 700__ $$0(orcid)0000-0002-5457-3694$$aPobes, C. 000032200 700__ $$0(orcid)0000-0001-8732-8196$$aPuimedón, J.$$uUniversidad de Zaragoza 000032200 700__ $$aRedon, T. 000032200 700__ $$0(orcid)0000-0002-7552-1228$$aSarsa, M.L.$$uUniversidad de Zaragoza 000032200 700__ $$aTorres, L. 000032200 700__ $$aValko, P. 000032200 700__ $$0(orcid)0000-0003-0228-7589$$aVillar, J.A.$$uUniversidad de Zaragoza 000032200 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
