dc.descriptionSe analizaron las propiedades de centelleo para espectrometría gamma de radón y sus descendientes, de un monocristal deperovskita de óxido de Al-Y copado con Ce, acoplado ópticamente a un fotomultiplicador Hamamatsu H5784 con un fotocátodobialcalino.Las pruebas se realizaron en agua hasta 100°C y en soluciones ácidas de HCl (37%), H2SO4 (48%) y HNO3 (65%) parasimular ambientes de interés geofísico como áreas volcánicas y geotérmicas.Medidas comparativas con fuentes estandard de radón del Instituto Nacional de Metrología de Radiaciones Ionizantes(ENEA) confirman las propiedades no-higroscópicas del centelleador y poca dependencia con el rendimiento en temperatura yHNO3.El monocristal muestra alta estabilidad para espectrometría gamma del radón en ambientes con grandes gradientes detemperatura y altas concentraciones de acidez.es-ES
dc.descriptionScintillation properties of a Ce-doped yttrium aluminium oxide perovskite monocrystal optically coupled to a HamamatsuH5784 photomultiplier are analyzed with a standard bialkali photocathode for radon and radon daughters gamma-ray spectrometry.Tests in water up to 100°C and in acidic solutions of HCl (37%), H2SO43 (65%) were performed to simulateenvironments of geophysical interest, such as geothermal and volcanic areas. Comparative measurements with standard radonsources provided by the National Institute for Metrology of Ionizing Radiations (ENEA) confirm the non-hygroscopic propertiesof the scintillator and small dependence of the light yield on temperature and HNO3.The Ce-doped yttrium aluminum oxide perovskite monocrystal shows high response stability for radon gamma-rayspectrometry in environments with large temperature gradients and high acid concentrations.en-US
