Determination of Radium 226 in mexican phosphate fertilizers and gypsum by gamma spectrometry
Description
The 226 Ra isotope was determined in 17, 20 and 46% m/m phosphate fertilizers and gypsum. The samples of the fertilizers were dissolved in 10% v/v nitric acid solutions. The barium sulphate method was used for the precipitation of 226 Ra. On the other hand, alkaline fusion method was used to separate the 226 Ra from gypsum. The results indicated that 226 Ra was present in the phosphate fertilizers and gypsum. The 226 Ra concentrations present in these materials were between 10 -4 - 10 -5 μg g-1. (Author)
