Concerning factors affecting absorption and scatter of X-rays:
An increase in the density of a material results in an increase in the linear attenuation coefficient (LAC)
Increasing the atomic number of a material increases its half-value layer (HVL)
Reducing the tube voltage increases the LAC
Increasing the filament voltage reduces the HVL of a material
A narrow beam has a higher scatter-to-transmission ratio than a wide beam
