Development of 3H, 14C, 41Ca, 55Fe, 63Ni radiochemical analysis methods in activated concrete samples

Abstract Development of 3 H, 14 C, 41 Ca, 55 Fe and 63 Ni radiochemical analysis methods were carried out independently by two laboratories using both inactivate activated concrete samples. Two preliminary radioanalytical procedures for the non-volatile radionuclides ( Fe, Ni) one Thermal oxidation method volatile C) developed. The difficulties in development results are discussed.
