    WOS:000397699000009PubMed:28110022In this analytical work, some components (Sr, Ni, Mg, Fe, Zr, Cd, As, Ca, Br, Rb, Mn, I, Zn, Pb, T1, U and Ba) of soil samples collected in different locations in the surroundings of Karaman, Turkey were determined by photon activation analysis (PAA). This method is based on photonuclear reactions. (gamma,n), (gamma,2n), (gamma,gamma') and (gamma,p)-type reactions have been observed. The samples were irradiated with bremsstrahlutig photons produced by a clinical electron linear accelerator (cLINAC) for up to about 85 min. The PAA results were compared with those obtained by X-ray fluorescence (XRF).Akdeniz UniversityAkdeniz University [2014.03.0121.006]; TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [BIDEB 2214-A (1059B141500153)]This work was supported by Akdeniz University (Project Number: 2014.03.0121.006) and TUBITAK BIDEB 2214-A (1059B141500153)

    Preliminary results of Sr/Ca ratio study of teeth samples by photoactivation analysis

    In this paper, we have performed Photoactivation Analysis (PAA), a non-destructive method, which is used to determine elemental concentration of any sample. This paper presents the first use of this method in medical sciences in Turkey. The method was applied to the determination of Sr/Ca ratios in teeth. The collected teeth samples and standards (SrO and CaCO3) have been irradiated for a fixed time interval with high energy photons. The photons were generated by a clinical linear accelerator (cLINAC). The photon end-point energy was 18 MeV. The energy and the time interval were sufficient to achieve good activation. Afterward, the samples and standards have been analysed with gamma spectroscopic analysis by using an HPGe detector system. By analysing many samples, a database of Sr/Ca ratios will be created at Nuclear Research and Application Center (NUBA). In this paper we present a small subset of the already analysed data as an example of our capabilities and goal. We hope to set an example for future studies
