Full spectrum analysis, FSA, has been being widely used for the identification in environmental radioactive. In this work, firstly, FSA is developed to analyze the gamma backscattering spectrum on concrete to determine the component densities. The concrete samples are mixed of Portland cement, sand, gravel and water in the different proportions. The experiments are carried out by the radioactive source Cs137 (0.5mCi) and the detector NaI(Tl) 2 inch x 2 inch. The obtained results show that FSA would be a good approach to analyze the gamma backscattering on concrete.
