Bu çalışmada, bağlayıcı olarak MnO2 ve borik asit, şeker, nişasta ve selüloz kullanılarak hazırlanacak farklı matrisler için spektral şiddet oranlarının değerlendirilmesi düşünülmüştür. Mn K X-ışını ile Compton ve koherent saçılma piklerinin altındaki alanlar hesaplanmış ve farklı şiddet oranları ile seyreltilmiş numunelerin ortalama atom numaraları arasındaki ilişki incelenmiştir. Hedefleri uyarmak için 100 mCi Am-241nokta radyoaktif kaynak kullanılmıştır. Hedeflerden yayılan ve saçılan X-ışınları bir ULEGe dedektörü ile sayılmıştır. Farklı seyrelticiler kullanılarak hazırlanan matrislerin ortalama atom numaralarının saçılma şiddet oranlarındaki değişimleri grafiksel olarak çizilmiş, elde edilen kalibrasyon eğrileri ve korelasyon katsayıları yorumlanmıştır. Ayrıca hazırlanan örnek grubunun Icoh+IComp/(μ/ρ)(Kα) yoğunluk oranı ile ortalama atom numarası arasında üçüncü dereceden polinomsal bir ilişki bulunmaktadır. Elde edilen kalibrasyon eğrileri aynı matrise sahip örnek gruplarında nitel analiz için kullanılabilir.

Investigation of The Standardization Method with Scattered X-Rays in Matrices Prepared with Different Diluters

Öz

In this study, it is considered to evaluate the spectral intensity ratios for different matrices to be prepared using MnO2 and boric acid, sugar, starch and cellulose as binders. The areas under the Compton and coherent scattering peaks with Mn K X-ray were calculated and the relationship between different intensity ratios and the mean atomic number of diluted samples was investigated. 100 mCi Am-241point radioactive source was used to excite the targets. The emitted and scattered X-rays from targets were counted by a ULEGe detector. The changes in the scattering intensity ratios of the mean atomic numbers of the matrices prepared using different diluents were plotted graphically, the calibration curves and correlation coefficients obtained were interpreted. In addition, there is a third-degree polynomial relationship between Icoh+IComp/(μ/ρ)(Kα) intensity ratio of the prepared sample group and mean atomic number. The obtained calibration curves can be used for qualitative analysis in sample groups with the same matrix.
