Abstract

• The aim of this research work is to investigate the radionuclides and calculate the activities of the collected samples from Kan Toke coal mine areas, Minhla Township, Magway Region. The radionuclide concentrations in soil samples were examined by using NaI (Tl) gamma ray spectrometry. There are four soil samples. From the analysis of the obtained spectra, peaks of 212Pb (77.11 keV), 212Pb (238.63 keV), 228Ac (338.32 keV), 208Tl (583.19 keV), 208Tl (860.56 keV), 214Bi (1120.3 keV) and 40K (1461 keV) were found. It is also found that the observed radionuclides except 40K (1461 keV) are the decay products of 238U and 232Th natural radioactive series. The concentrations of these radionuclides were determined by Gamma Vision 32 software. The highest activity of 212Pb (77.11 keV) was found in soil sample 1. The highest activity of 212Pb (238.63 keV) was found in soil sample 3. The highest activity of 228Ac (338.32 keV) was found in soil sample 3. The highest activity of 208Tl (583.19 keV) was found in soil sample 3. The highest activity of 208Tl (860.56 keV) was found in soil sample 1. The highest activity of 214Bi (1120.3 keV) was found in soil sample 1. The highest activity of 40K (1461 keV) was found in soil sample 4. The concentrations of radionuclides contained in Kan Toke coal mine areas are not very high compared with IAEA standard, the samples have very small amount of radionuclides.
