This study focused on the performance of where elements analysing techniques were used to detect the elements in granite stones. These techniques are NAA (neutron activation analysis) and XRF (X-ray fluorescence). They were applied to detect the elements in samples which had been chosen from different areas of Pulua Penang in Malaysia collected by geophysics group which helped to describe and identify the elements found in the granite stone that were used in the study procedures to control the analytical results. The integration of both methods has enabled the researcher to determine 40 elements in the samples. The numbers of elements detected by XRF analysis method are 12 elements (Ar, K, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn); while, the elements detected by NAA method have three folds of elements with XRF analysis method were 35 elements (Na, AI, Si, K, Ca, Sc,Ti, Mn, Fe, Co, Ga, Ce, As, Br, Rb, Zr, Sb, I, Cs, Ba, La, Nd, Sm, Eu,Tb, Dy, Yb, Lu, Hf, Ta, W, Au, Pa and Np). Seven common elements were detected in both techniques: K, Sc, Ti, V, Mn, Fe and Co. Si has a higher concentration in NAA technique which is 331.8 ppm. Sc has a lower concentration in XRF technique which is 0.25 ppm. Nd has a lower concentration in NAA technique which is 3.09 - 10-5 ppm. Finally, it is found that the NAA is better to detect the elements than XRF. 展开更多
