Description

A selective analysis method was performed for thorium and uranium isotopes. Modifications were added to the conventional methods in order to improve the chemical yield and to reduce the detection limit. This reduction improve the assessment of internal contamination in ocuppationally exposed workers. (Author)

Abstract (Portuguese)

Otimizou-se um metodo que permite a analise seletiva de isotopos de torio e uranio. As modificacoes introduzidas nos metodos convencionais, proporcionaram ao metodo desenvolvido uma eficiencia radioquimica elevada, o que consequentemente reduziu o limite de deteccao. Esta reducao permitira um melhor acompanhamento da excrecao destes radionuclideos incorporados em trabalhadores ocupacionalmente expostos. (Autor)
