Abstract

The article describes the technique of reactor production and identification of the radioisotope 103Pd, and the conditions for dissolving metallic palladium irradiated in the reactor and applying it to the ion-exchange column are selected. Experimental results of the efficiency of 103mRh washing from the ion-exchange column with anionite Eichrom 1× 8 with a particle size of 200–400 Mesh in Cl– form for several variants of its accumulation and elution are obtained. The value of the impurity activity of 103Pd in the eluate with 103mRh is measured. The stability of the ion-exchange column with repeated conditions of washing and accumulation of 103mRh for approximately 1 month of its operation is demonstrated.
