| Research Abstract |
This study uses analysis method that can identify a multi element at the same time from gamma rays discharged by irradiating the neutron to the sample. This study proposes the non-destructive method of measuring the profile of the chloride ion concentration in concrete necessary for predicting the progress of deterioration by the reinforcement corrosion of a concrete structure by gradually changing the irradiating angle of neutron beam to the concrete surface. The proposal method can apply to arbitrary distribution of the chloride ion concentration and is appropriate.
