Figure 8

Effective attenuation coefficient assessment. The figure shows the experimental setup for the determination of the effective attenuation coefficient μ ∧ . The profile in the energy window (50, 150 keV) recorded on the camera equipped with a MEGP collimator is the result of two kinds of X-ray paths: (a) 90° scattering in the water and (b) penetration through the camera shielding and collimator septa.
