Density of lung varies between 0.25 to 1.0g/cm3 and bone density is 1.8g/cm3

When treating with a single photon field using higher energies will cause less superficial dose

Depth-dose characteristics of electrons have unique features that allow full dose superficially while sparing almost all tissue beyond the target
