Abstract

We have started the development of a transportable neutron salt-meter, we call it RANS- μ , combining a 252 Cf neutron source and a prompt gamma neutron activation analysis. Trials of chloride detection measurement with RANS- μ were performed outdoor using removed bridges damaged by chloride attack at an outdoor yard in Public Works Research Institute (PWRI) and a test bridge in Fukushima Robot Test Field. For the measurement at PWRI, the results obtained by RANS- μ were compared with those of the automatic potentiometric titration by drilled powder, and then consistent results were obtained.
