| Publisher Description: This study focused on the performance of where elements analyzing techniques were used to detect the elements of Granite stones. Neutron Activation Analysis (NAA) and X-Ray Fluorescence (XRF) were applied to study the elements in the samples which were chosen from different areas of Penang Island in Malaysia colleted by geophysics group. Certified reference materials, which helped to describe and identify the elements found in the Granite stone, 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 use of XRF analysis with Americium-241 (Am-241) as an excitation source which has an excitation energy and activity equal to 59.53 KeV, 100 mCi, respectively. All the samples were exposed to gamma radiation for 24 hours with constant thickness (3 mm) and different weights from 8.7 to 13.34 g. On the other hand, the researcher has carried out the experiments under the certain procedures. The researcher has used NAA with the source (Am-241, Ba-133) as an excitation source but with different excitation energy (10 MeV) using Rector of Malaysia(Mint). |
