Abstract

High radiation above the Earth is mainly due to naturally occurring radioactive elements in the Earth's crust and are concentrated in granites. Granites on the other hand are widely used in the constructions of houses, buildings, and even as ornamental stones. This study investigates the possible radionuclide present in the granites of the northern Peninsular Malaysia and the potential hazard associated with them. Thirty nine samples were taken from random locations in Penang, Perak and Kedah to measure their aplha, beta, and gamma radiation present. Eleven of them with significant radiation counts were taken for further analysis as to predict in more detail of the possible radionuclide present based on the alpha, beta and gamma radiation measured. The radionuclide predicted are based on the three prominent radioactive series of the natural radioactivity and Potassium-40. Most of the samples are predicted as to have Potassium-40 and several other radionuclide of the Uranium and Thorium series of long half-life. The results then can be used to investigate the potential health hazard of the granite samples are of the radionuclide present. High activity of radiation is measured in the granites Bayan Lepas Waterfall, Bukit Hijau, Hot Spring, Kampar, Kampung Raga, Kuala Woh, Lata Mengkuang and Shamrock Beach.
