Study of the Granulation Influence on Uranium Content in Sedimentary Phosphate Samples by using CR-39 and LR-115 Solid State Nuclear Track Detectors

摘要

Different samples have been taken from different layers in a sedimentary phosphatic deposit and sieved. Different granulometric fractions have been selected Uranium contents of each phosphate sample and its corresponding selected fractions were determined by using CR-39 and LR-115 solid state nuclear track detectors (SSNTD), Correlation between fraction grain diameter and uranium enrichment factor has been investigated. The different selected fractions of the studied phosphate samples were analysedoptically. A relationship between uranium content and fraction's composition was found.
