摘要

A nondestructive test method for detecting chlorides in concrete has been developed based on prompt gamma neutron activation (PGNA). Its performance has been modeled using a hybrid MCNP/optical ray tracing approach. Since the chlorides often come from de-icing salts applied to the concrete surface, the Cl concentration has a non-linear depth profile which is typically modeled by the erfc function. The signals from this distribution have been simulated for several significant Cl capture peaks to estimate the erfc function parameters.
