1. Principle of the technique

1.1 Bases

X-ray radiography is based on Beer-Lambert's law, which calculates, along a given X-ray path within matter, the ratio between the number of transmitted photons N and the number of incident photons N ₀ . As the expression (1) shows, this number depends on the absorption (or linear attenuation) coefficient µ (in m ^-1...
