Abstract
The objective of this study were to analyze the specific activity of the natural radioactive nuclide of 226Ra, 232Th and 40K and to calculate the Radium equivalent activity (Raeq), the Internal hazard index (Hin), the External hazard index (Hex), the Gamma-absorbed dose rate (D) and the Annual external effective dose rate (E) in the 20 soil samples from Koh Phangan District, Surat Thani Province by using gamma-ray spectrometer with a high purity germanium detector (HPGe). The results show that the specific activity of radioactive nuclides in many samples were higher than Thailand and the global average values. In addition, the Radium equivalent activity (Raeq), the Internal hazard index (Hin), the external hazard index (Hex) and the gamma-absorbed dose rate (D) were higher than the UNSCEAR criterion (2000). The present study found that the radioactivity may affect the health of people living in that area.
