Abstract
This study investigated the radioactivity levels of locally consumed tobacco and three (3) popular brands of cigarettes. The Ortec X-ray fluorescence spectroscopy (XRF) with model number XL12170 was used to determine the radioactivity and elemental composition of each of the samples. All the samples were found to be radioactive with the following elements, including-K, Ca, Ti, Cr, Mn, Fe, Pb, Rb, Sr, Zr and Nb. From the analysis, it was observed that the locally consumed tobaccos have a higher radioactive nature than the selected brands of cigarettes and this was ascribed to their different methods of processing/ techniques.
Key words: Radioactivity, background radiation, X-ray fluorescence spectroscopy, radioactive elements, alpha radiation.
