Unilateral NMR: a Noninvasive Tool for Monitoring In Situ the Effectiveness of Intervention to Reduce the Capillary Raise of Water in an Ancient Deteriorated Wall Painting
Figure 4
Moisture distribution maps obtained by unilateral NMR at a depth of 0.1 cm (left) and at a depth of 0.5 cm (right). Top: maps collected in February 2008 before the intervention to reduce the capillary raise of water through the walls. Middle: maps collected in November 2009 four months after the intervention and in the presence of a scaffolding site in the proximity of the wall painting. Bottom: maps collected in February 2010 seven months after the intervention and after removing the scaffolding site.
