Fast source preparation for alpha-spectrometry of uranium and transuranium isotopes

One of the most important problems related to the high background area is that of environmental contamination. Therefore a number of local plants from Kasar in Köprüba?i as referred to high background area, West Anatolia, were investigated for their uranium contents as well as for other elements by using instrumental neutron activation analysis (INAA). All of the plants except wheat samples contained levels above 0.6 ppm U which is the average background concentration of uranium in the ashed samples of living plant material. Beside the uranium, the concentrations of the other trace elements such as Ce, Ba, Cr, La, Sc, Rb, Fe, Zn, Zr, Eu, Co, Cs, Br, As, Na, K, in the plant ashes were also determined.
