A reference range was established as a function of sex and considering lifestyle factors (nonsmokers and non- drinkers). For both regions lower values of K were found in females when compared to males and lower values of Na were found in males compared to females. Increasing trends for Na and Br were observed in the Northeast region.95-97openAccessbrazilbloodcalibration standardsbrominechlorinepotassiumsodiumneutron activation analysisbiochemistryradiation hazardstoxicitybiological materialsArtigo de periódico128210.1007/s10967-009-0276-3https://orcid.org/0000-0001-7766-2692
