dc.description.abstract [EN] A radiochemical procedure has been developed for the quantification of uranium and thorium isotopes in NORM samples from the ceramic industry, such as zirconium sands, zirconium flours, micronized zircon, pigments and personal aerosol filters. The method is based on a fusion pretreatment with borate salts, a separation with anion exchange resins and alpha-particle spectrometry measurement. This method is an alternative to gamma spectrometry when the amount of sample is extremely small (2-10 mg) as in the case of aerosol filters, or there is no secular equilibrium in the 238U and 232Th chains, as in the ceramic pigments. The method has been validated with different ceramic materials and the comparison of the results with gamma measurements. Its reproducibility was also checked with different sample masses. es_ES
dc.description.sponsorship The authors are grateful to the Generalitat Valenciana for the financial support received by funding the projects "Characterisation and radiological measurement of suspended dust in the ceramics industry in the Valencian ceramic industry in the Valencia Region" (AICO/2020/106) and "Assessment of the radiological impact due to the presence of radioactive material in suspension in activities of the Valencian ceramic industry" (CIAICO/2021/290). As well as to the FEDER funds (IDIFER/2021/047) for the support through grants for R&D&I infrastructure and equipment.DAS:The data are available from the corresponding author on reasonable request. es_ES
