In these years older buildings are renewed in most European countries on a large scale, and new techniques are needed for both inspection and eradication of fungal attacks. Heat treatment as a means of eradicating the dry rot fungus has been used in Denmark during the last decade. This technique minimises the structural damage to the building, whilst at the same time reducing costs by up to 50%. To utilise these advantages, there is a great need for new methods of non-destructive inspection of buildings. Two techniques have been developed: the snifferdog and Radiological Density Scanning. This paper describes the RDS inspection technique in comparison with a commercial tool, the Decay Detecting Drill developed to detect decay and other defects in living trees and timber. As part of the EUREKA Euroenviron project entitled Decay Control coordinated by Danish Technological Institute new methods of identification and detection of the early stages of fungal attacks are being developed and tested.
