Abstract

• This research work was to analyze the content of radionuclide in coal ash sample which collected from Myanmar Elephant cement factory, Pathein Gyi Township, Mandalay division. The HPGe detector was used for the study of radionuclide in coal ash sample and analyzed by using Gamma Vision-32 software. The radionuclide present in coal ash sample such as Bi- 207, U-235, Ac-228, Pb-212, Pb-214, Tl-208, Bi-214 and K-40 were observed. But Bi-207 and K-40 do not exactly present in coal ash sample. The radionuclide (Ac-228, Pb-212, Pb-214, Tl-208 and Bi-214) found in the measured sample was the daughter nuclei of Actinium, Uranium and Thorium series. U-235 is the parent nucleus of Actinium series. It is expected that Actinium, Uranium and Thorium are concentrated in coal ash sample.
