Title

Measurement of Radioactivity of Surface Soil in the East of Shazand Power Plant

Pages

  109-119

Abstract

 Background and Objective: Human beings are always exposed to ionizing radiation. One of the sources of this radiation is the nuclear radiation from terrestrial radioactive nuclide in water, Soil, rock and plants. Nuclear radiation emission from radionuclides causes diseases like cancer and genetic abnormalities. Therefore, studies of Soil Radioactivity are of great importance. Method: In this research, 34 Soil samples were studied between the Shazand Power Plant and Arak city. The specific activities radionuclides were determined using gamma ray spectrometry method, with employing a high purity germanium detector (HPGe) model GCD30195 with 30% relative efficiency. Finding: The specific activity of 226Ra, 232Th, 40K and 137Cs in these samples varied from 18. 92± 1. 91 to 43. 11± 2. 69, 25. 31± 2. 16 to 54. 27± 3. 65, 230. 17± 9. 96 to728. 25± 18. 03 and <1. 49 to 9. 52± 0. 88 in Bq/kg respectively. Absorbed dose rate in air one meter height from ground and Radium Equivalent were calculated as 4. 57± 1. 38 to 79. 68 ± 2. 07 in nGy/h and 84. 14± 3. 08 to 157. 74± 4. 50. Conclusion: The average of Radium Equivalent for Soil samples was calculated as 116. 38± 18. 38 Bq/kg which is the same level of world average (131. 69). Maximum Radioactivity observed in 3 to 7 km distance from Power Plant. The results of this study indicate that the radiation of the Soil does not pose a threat to the health of the inhabitants.
