METHODS OF NON-DESTRUCTIVE WOOD TESTING
2.4. Neutron radiography/tomography and synchrotron light
A visualisation of water in wood is detectable with neutrons. The dimension is in the cm range
(neutrons), mm range (synchrotron); with synchrotron light, a higher resolution is possible. The
maximum sample dimension is in the mm range (Fig. 9, 11).

2.5. Mechanical properties
Fig. 11 and 12 shows tools than can measure the penetration depth (to detect defects on the surface
area) and the drilling resistance (to detect fungal decay).
