Paper Abstract
The maintenance and repair of reinforced concrete structures, especially those submerged in the sea-water, require
effective inspection and monitoring techniques for assessing the state of corrosion in reinforcement material. An
underwater inspection system was developed which is able to monitor the reinforcement corrosion. The system is ROV
equipped with the sealed tube neutron generator (NG). By rotating the NG and by using the associated alpha particle
technique it is possible to measure the concrete cover depth together with the reinforcing bar diameter. The possibility to
estimate the carbon and chloride content in the concrete was investigated. Iron plates of different thickness, covered by 6
cm thick concrete block, were successfully detected and the thickness of the concrete cover was estimated. In addition,
reinforced bar of one and three centimeters in diameter was identified and measured.
