X-Rays: Energy Deposition in a Nutshell
 X rays are ionize indirectly.
 On interaction, energy is scattered or
transferred to electrons, then absorbed.
 Biological effect depends on the amount
of energy absorbed (dose ).
 Tracking electrons is highly important for
accurate dose calculations.
 One treatment (2Gy) requires ~108-9
incident x rays per mm2.
