Description
A radiographic technique for the nondestructive examination of cultural heritage artefacts (mainly metal or stone statues). The radiation source is a sealed radioactive source (iridium 192 or cobalt 60) set in a gamma radiography projector. The gamma rays will penetrate different composition/density materials to varying degrees. The resulting variations of transmission of these radiations are recorded by a detector, generaly a radiographic film. The resulting gamma radiograph shows the differential absorption pattern, useful for examining an object internal structure : homogeneity of the constitutive material, voids, cracks, inserts, mechanical assembly processes, previous restoration or modification...
