Assessment of natural radioactivity and mass attenuation coefficients of brick and roofing tile used in Turkey
Damla, N.; Cevik, U.; Kobya, A. I.; Celik, A.; Celik, N.; Yildirim, I. (Pergamon-Elsevier Science Ltd, 2011)In this study the distribution of natural radionuclides ((226)Ra, (232)Th, (40)K) in brick and roofing tile samples commonly used as building materials in Turkey was measured by using gamma spectrometry. The activity ... -
Decaying source model: Alternative approach to determination of true counting rates at X and gamma ray counting systems
Karabidak, S. M.; Cevik, U. (Pergamon-Elsevier Science Ltd, 2013)The counting systems consisting of electronic devices are used for detection of radiation due to X or gamma rays. The dead time of the counting system is based on time limitations of these electronic devices. The dead time ... -
Determination of proper peaking time for Ultra-LEGe detector
Karabidak, S. M.; Kaya, S.; Cevik, U.; Celik, A. (Pergamon-Elsevier Science Ltd, 2011)Reducing count losses and pile-up pulse effects in quantitative and qualitative analysis is necessary for accuracy of analysis. Therefore, the proper peaking time for particular detector systems is important. The characteristic ... -
The effect of energy resolution of detection instrument on mass attenuation coefficient
Celik, N.; Ozen, S. A.; Demirtas, O. F.; Cevik, U. (Iop Publishing Ltd, 2018)The effect of energy resolution of two detection systems, HPGe and NaI(T1), was determined by Monte Carlo (MC) calculation on mass attenuation coefficients of magnesium (Mg) and tungsten (W). In order to reveal the energy ... -
Elemental and radioactivity analyses of mosses collected in hatila valley national park - Eastern black sea region of Turkey
This study was performed in one of the most important parks of Turkey, the Hatila national park, where a gold mining activity is planned to be conducted. For this purpose, 40 moss samples were collected for heavy metal and ... -
Heavy metal analysis by moss species in the Black Sea region of Turkey
Koz, B.; Cevik, U.; Bulut, V.N.; Kaya, S.; Gundogdu, A.; Celik, N. (2013)The heavy metal analysis of mosses in the Black Sea region of Turkey was determined using atomic absorption spectrometry method. The procedure was also validated by analysis of standard reference material (IAEA-336 Lichen). ... -
Indoor radon and gamma spectrometric measurements for the Erzincan Basin on North Anatolian Fault Zone, Turkey
Kucukomeroglu, B.; Ozturk, E.; Damla, N.; Celik, N.; Duran, S. Uzun; Cevik, U.; Albayrak, N. (Sage Publications Ltd, 2016)Indoor radon and soil radioactivity levels were determined for Erzincan province in Turkey. Indoor radon concentrations were determined in 89 dwellings using CR-39 passive Solid State Nuclear Track Detectors (SSNTDs) for ... -
Radioactivity measurements in spas of central and Eastern Black Sea region, Turkey
Duran, S. U.; Kucukomeroglu, B.; Cevik, U.; Celik, N.; Taskin, H.; Ersoy, H. (Ijrr-Iranian Journal Radiation Res, 2019)Background: The aim of this study is to measure the level of radon gas in the thermal springs of the four seasons in the Black Sea Region and to determine the gamma activity levels in the soils around them. Materials and ... -
Radiological characterisation of Artvin and Ardahan provinces of Turkey
Kucukomeroglu, B.; Yesilbag, Y. O.; Kurnaz, A.; Celik, N.; Cevik, U.; Celebi, N. (Oxford Univ Press, 2011)Indoor radon concentration measurements were carried out and corresponding annual effective doses due to exposure to indoor radon were determined in Artvin and Ardahan provinces located in the eastern part of Turkey. The ... -
Virtual point detector for HPGe detectors for 26.6-1332 keV photon energies by experiment and Monte Carlo simulation
Celik, N.; Cevik, U.; Kucukomeroglu, B. (Springer, 2012)Variation of virtual point detector (VPD) position inside HPGe detector as a function of source photon energy for the energy range from 26.6 to 1,332 keV was investigated. Although VPD concept was well established for HPGe ...
