Abstract
Uranyum ve toryum cevher analizleri için radyoizotop x- ışını fluoresans tekniğinin hassasiyetini etkileyen teorik ve deneysel faktörler üzerinde ayrıntılı olarak çalışılmıştır. Teorik olarak, matematiksel istatistiğe dayanan minimum tayin edilebilirlik sınırı veren formül üzerinde durulmuştur. Uranyum ve toryum tayini için en iyi deney sistemi Cd-109; Si (Li) olarak belirlenmiştir. Tayin edilebilirlik sınırı 1000 s. süre için uranyum cevherlerinde yaklaşık 13ppm ve toryum cevherlerinde 108 ppm olarak saptanmıştır.
For the analysis of uranium and thorium ores, the theoretical and experimental factors that affect the sensitivity of the radioisotope x - ray fluorescence technique were throughly studied. Theoretically, the minumum detection limit formula based on mathematical statistics was tried. For uranium and thorium ore analysis, the optimum system conditions were determined. Cd-109; Si (Li) system was found to be the most suitable system. The minimum values for the limits were approximately found to be 13 ppm for uranium and 108 ppm for thorium ores in 1000 sec.
