The purpose of the study was to determine the existence of cavities caused by termites in the wood beams hidden inside the ceiling of the Domstic Chapel, built in 1666, in the city of Córdoba, Argentina.

 

Given the small difference in density (which determines the contrast of Gammagraphic images) between the wood and the areas attacked by termites (empty spaces with waste of termites), simulations GAMMASIM were performed to determine the feasibility of using our technology in this case. It was estimated to be determined larger cavities to 3 cm in the direction of radiation.
