Abstract: The radiological hazard assessment in 114 surface soil samples collected from 8 districts from Krabi province in southern region of Thailand, have been studied and evaluated. It was found that the average values of four radiological hazard indices which are gamma absorbed dose rate (D) radium equivalent activity (Raeq), external hazard index (Hex), and annual effective dose rate (AEDout), were equal to 89.16 ± 9.53 nGy/h, 186.35 ± 19.50 Bq/kg, 0.50 ± 0.05 and 0.11 ± 0.01 mSv/y, respectively. Furthermore, the results were also compared with Thailand and global radioactivity measurement and evaluations. Moreover, the radioactive contour maps of Krabi province were also created by using the results.
