Assessment of Radiological Levels at Schools in Trabzon, Turkey
Cevik, Ugur; Celik, Ahmet; Celik, Necati; Ozkalayci, Fatih; Akbulut, Songul (Sage Publications Ltd, 2013)In this study, a survey on environmental radioactivity in 16 high schools located in north eastern region of Turkey (the black sea region, province of Trabzon) was carried out. Indoor air radon (Rn-222) concentrations were ... -
Building-up a code for the purpose of TRUE coincidence summing correction in gamma-ray spectrometry with EGS4
Celik, Necati; Altin, Duygu; Cevik, Ugur (Pergamon-Elsevier Science Ltd, 2015)In the presented study, a code was created for the purpose of true coincidence summing (TCS) correction factors for Cs-134. The created code was implemented in EGS4 Monte Carlo simulation package. TCS factors were determined ... -
Effect of detector collimation on the measured mass attenuation coefficients of some elements for 59.5-661.6 keV gamma-rays
Celik, Necati; Cevik, Ugur; Celik, Ahmet (Elsevier, 2012)Mass attenuation coefficients were determined experimentally for Sc, Ni and W for gamma energies of 59.5, 122, 276, 302, 356, 383 and 662 keV for different detector collimator diameters ranging from 2 to 10 mm. The aim was ... -
ELEMENTAL AND RADIOACTIVITY ANALYSES OF MOSSES COLLECTED IN HATILA VALLEY NATIONAL PARK - EASTERN BLACK SEA REGION OF TURKEY
Koz, Bahadir; Cevik, Ugur; Celik, Necati (Parlar Scientific Publications (P S P), 2012)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, Bahadir; Cevik, Ugur; Bulut, Volkan Numan; Kaya, Selim; Gundogdu, Ali; Celik, Necati (Parlar Scientific Publications (P S P), 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). ... -
A New Approach for Determination of Volumetric Water Content in Soil Samples by Gamma-Ray Transmission
Celik, Necati; Altin, Duygu; Cevik, Ugur (Springer International Publishing Ag, 2016)A new method was presented for the purpose of volumetric water content determination in any soil sample by gamma-ray transmission. Monte Carlo (MC) simulation technique was used to determine the functional behavior of the ... -
