Radioisotopes of uranium, thorium and plutonium in water, soil and fertilizer samples, have been chemically separated and determined by alpha-spectrometry method. Radiochemical Procedure involving ion-exchange, enabled to determine these isotopes in very tow concentrations (under 50 mu Bg/g). U-232, Th-229 and Pu-238 were used as a tracers for radiochemical yield recoveries (up to 90%). Thin layer sources have been obtained by electrodeposition.
