“…In a similar work, soil gas radon changes were found between 25 and 420 kBq m − 3 in Slovenia [13]. Our earlier study on Tuzla Fault which is very close to Izmir revealed that soil gas radon concentration values ranged from 0.1 to 261.1 kB m − 3 [14].…”

Measurements of 222Rn and 220Rn activity were carried out along the Pınarbaşı segment of the Izmir fault (IF) to get new information on the Izmir Fault (IF) and its seismicity. İzmir Fault is one of the most important active tectonic structures in Turkey's Active Fault Map. Due to very intense urbanization, there is not enough information about the fault. This study also discusses the usability of the 222Rn/220Rn ratio as a geodynamic precursor.

“…It is a colorless, odorless, naturally occurring, chemically inert and radioactive gas [2,3]. It is originated from the deep layers of earth crust and moves to the atmosphere by diffusion and convection or advection [4,5,6]. It is recognized as one of the most important environmental indicator or precursor for being a noble gas and a member of radioactive decay series [7].…”

Radon which occurs in uranium decay series is a noble gas and it moves from the deeper layers of the earth crust to the atmosphere. Formation of the radon gas in the Earth's crust and its migration to the atmosphere are quite a complex process due to the external factors like tectonic movements, meteorological factors etc. In this process, both the advection and diffusion are effective mechanisms for radon transport. But, the most effective mechanism is diffusion. In this study, radon diffusion of soils taken from Küçük Menderes Basin was investigated by controlled laboratory experiments and the radon diffusion coefficient of these soils was calculated. Soil gas radon measurements were performed by LR 115 Type 2 solid state nuclear track detectors.

“…There are more than 230 great groups described in the world (USDA 1999;İçhedef et al 2013). In the Aegean Region of Turkey, there are 13 great soil groups to be defined by The Ministry of Agriculture and Rural Affairs of Turkey (2011).…”

In this study, measurement of natural radioactivity and analyses of physical properties of soil were carried on great soil groups around the Seferihisar Geothermal Region. The radioactivity levels in soils were analyzed using scintillation gamma spectroscopy. The activity concentrations for 226 Ra, 232 Th, and 40 K range from 7.1 to 32.0 Bq kg -1 , 15.2 to 35.9 Bq kg -1 and 223.1 to 802.2 Bq kg -1 , respectively. Obtained data was compared with average values given by UNSCEAR and the other studies. The radium equivalent activity (Ra eq ) in soil samples ranges from 42.2 to 144.7 Bq kg -1 which are lower than the suggested maximal admissible value of 370 Bq kg -1 recommended by OECD. In addition, the value of external exposure dose has been determined from the content of natural radionuclides in soil. The absorbed dose rates change between 20.6 and 70.9 nGy h -1 with a mean value of 46.7 nGy h -1 which is lower than the global average value of 55 nGy h -1 . The annual effective dose rates varied from 25.2 to 87.0 lSv year -1 with an average value of 57.3 lSv year -1 . Obviously, all the calculated values were lower than this value, and therefore the environment of Tuzla Fault can be regarded as an area with normal natural background radiation.
