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