    ABSTRACT: The muscles and livers of the ten rainbow trouts (Oncorhynchus mykiss; N, 1752) obtained from Sapanca, Aquaculture Facility of Aquatic Products Faculty, The University of Istanbul (Turkey), have been analysed quantitatively for some minor elements using the radioisotope energy dispersive X-ray fluorescence (EDXRF) and neutron activation analysis (NAA) methods. It was found that samples contain Na, K, Ca, Sc, Cs, Fe, Co, Cu, Zn, Se, Br, Rb, Sr, Au, La and Ce in different amounts. Comparison of the results with those of reference river fish samples indicated that agricultural rainbow trout samples from Sapanca region have higher Fe level.

    ABSTRACT: High resolution γ-ray spectroscopic investigation of a mineral sample obtained from the deposits of the Basoren area, which is located about 670 km south-east of Ankara (Turkey), within the north-eastern margin of the eastern Tauride range, is reported. The γ-spectrum of the natural sample shows all the elements of the Th decay series and a few elements of U decay series. On the other hand, the γ-spectrum of the sample irradiated by 14.5 MeV neutrons additionally gives Na, K, Sc, Cr, Mn, Kr, Sr, Y, Zr, Xe, La, Ce, Pr, Nd, Sm, Eu, Gd, Tm and Yb peaks. The natural α and β radiations of the mineral sample for are found to be Aα=1.72 MBq kg−1 and Aβ=0.40 MBq kg−1, respectively, which is consistent with the γ-spectroscopic results of the Th decay series. The X-ray fluorescence analysis of the sample is also given.
