Development of a sequencial analysis method for determining U-238, U-234, Th-228, Th-230, Ra-226 and Ra-228 in environmental samples
AbstractAbstract
[en] A method of sequential analysis was developed aiming to determine U-238, U-234, Th-232, Th-230, Th-228, Ra-226 and Ra-228 in environmental samples, and was applied to the analysis of mineral waters from the Pocos de Caldas Plateau. The highest values were found in samples from Aguas da Prata city, which had up to 63 pCi Ra-226/1. The minimum detectable activities were lower than 0,1 pCi/1 for uranium and thorium isotopes and about 0,5 pCi/1 and 2pCi/1 for Ra-226 and Ra-228 respectively. (Author)
