Description
The main purpose of this research work is to investigate the natural radiological hazard of
sediment samples from Doathtiwati River, near Mandalay city. The sediment samples were
collected from five different places in 7 mile mini beach, Mandalay, have been investigated
by Gamma Spectroscopy. The collected sediment samples were measured by NaI (Tl)
detector and analyzed by gamma vision 32 software. The some natural radionuclides are
present in all sediment samples. The natural radionuclides such as 208Tl (75.77keV), 212Pb
(238.63keV), 214Pb (351.93keV) and 208Tl (583.19keV) were identified. According to the
analyzed data, the radionuclide 208Tl (75.77keV) concentration is the highest value in all the
radionuclides of sediment samples. According to the value of external hazard index and
absorbed dose rate, it is in the good agreement for the recommended value of UNSCEAR
2000, Hex <1. So, it can be assumed that it is not hazard to the surrounding.
