Nondestructive Detection of Biodegradation in Wooden Construction

-Detection of Rot and Cavity using Radar Technique-

Scanning using portable radar apparatus was applied to detect biodeterioration of wooden constructions nondestructively and the feasibility of the technique was compared with the drilling resistance measurement and the distribution of water content.
