“…In situ measurement were performed using a portable gamma-ray spectrometer (1024 channels) fitted with an BGO (Bismuth German Dioxide) detector [2,11,18]. The gamma ray spectrometer is shown in Fig.1 and it can separate gamma rays produced by the elements of 40 K, 238 U and 232 Th.…”

“…There are many studies in the literature due to be cause to serious health problems in humans the radiation levels of natural materials. Therefore, many researchers have measured the radiation levels of building construction materials in different countries [2][3][4][5][6][7][8][9][10].…”

“…The natural radioactivity levels present in soil and rock are due to the presence of radioelements, including uranium (238U), thorium (232Th) and potassium (40K). Radiometry is one of the most powerful and rapid methods to obtain information about the distribution and concentration of radionuclides (eU, eTh and K (%)) at any location [2]. Thus some previous researches [12][13][14][15][16][17] using this method indicate that it is also possible to perform radiological hazard, geological, geotechnical and geochemical mapping of a study area.…”

People have always been exposed to radiation and it is important to determine this radiation dose for radioactive contamination. The main source for this radiation is from earth and is can change with the geological structure. Isparta is an interesting area as it is Angle connects the Aegean-West Anatolian extensional section and it is bordered by two major fault zones. Thus radiation dose have been measured in vitro (in situ) in this area. The measurement has been performed using gamma spectrometer (GF Instruments) fitted with an NaI(Tl) scintillator detector. The spectrum can separate gamma rays due to the 238 U, 234 Th and 40 K and measure activity. From the in vitro measurements of radioactivity and absorbed dose, the annual effective dose (E d ) and radium equivalent activities (Ra eq ) were also obtained.

“…For this purpose, several studies have been carried out to measure the natural activity concentrations of 40 K, 226 Ra and 232 Th in different materials [3][4][5][6][7][8][9][10][11]. Natural radioactivity levels depend on the geological and geographical characteristics of the region.…”

“…The first three of them are called the natural decay series, and their members down to one of the stable isotopes of the lead are also radioactive. However, 137 Cs is a man-made radioisotope, released by nuclear weapon trails or nuclear power plant accidents, and its presence builds up radiation level in the nature [2]. It is well known that Turkey was widely effected the Chernobyl nuclear power plant disaster.…”

In order to determine the radioactivity level at Izmit Bay Marmara Sea, marine sediment samples were collected from five different locations. The radioactivity concentrations of naturally occurring 238 U, 232 Th and 40 K isotopes and also that of an artificial isotope 137 Cs were measured by using gamma-ray spectroscopy. Preliminary results show that the radioactivity concentrations of 238 U and 232 Th isotopes are lower than the average worldwide values while the radioactivity concentrations of the 40 K are higher than the average worldwide value. A small amount of 137 Cs contamination, which might be caused by the Chernobyl accident, was also detected.
