Concerning an X-ray beam:
It reduces in equal quantities as it passes through material of equal thickness
No matter how thick the material, it is not possible to completely absorb the primary X-ray beam
Beam hardening results from a reduced number of photons being removed from the primary beam
For a heterogeneous beam, the half-value layer (HVL) increases as the beam passes through the material
Wearing lead gloves protects the operator's fingers from the X-ray beam
