Penetration depth of protons
1. Introduction
Computational methods are www.epilepsy-brain-mind2014.eu determine the proton energy degradation and flux attenuation as a function of penetration depth in various rra terials.

Description:Initially, they transfer relatively small amounts of energy to the molecular electron clouds they pass through low degree of ionization. However, this process slows them down see Figure 1. Figure 2 The slower the particles, the greater the linear energy transfer and the braking effect become. This leads to an "energy explosion" known as the Bragg peak at the end of the particle's path, i. Unlike X-rays, proton radiation deposits a lower dose in front of the tumor. The tissue behind the tumor is not exposed to any radiation at all.
