Radiation is all around us. From radio waves transmitting information to the visible spectrum that gives our world color. Heck, even talking produces radiation in the form of sound. But what about the more dangerous forms of radiation: alpha and beta particles, gamma and X-rays? Radio waves, microwaves, infrared and ultraviolet.

Proton Therapy | inteligentnemiasto.com

Proton therapy is the most technologically advanced method to delivery radiation treatments to cancerous tumors available today. The unique characteristics of how protons interact within the human body allow it to deliver curative radiation doses while reducing doses to healthy tissues and organs resulting in fewer complications and side effects than standard radiation therapy. Understanding how proton therapy works provides patients and physicians with insight into the clinical advantages of this treatment modality. Fundamentally, all tissue cells are made up of molecules with atoms as their building blocks. In the center of every atom is the nucleus. Orbiting the nucleus of the atom are negatively charged electrons.

Stopping-Power & Range Tables for Electrons, Protons, and Helium Ions

Many nuclei are radioactive; that is, they decompose by emitting particles and in doing so, become a different nucleus. In our studies up to this point, atoms of one element were unable to change into different elements. That is because in all other types of changes we have talked about only the electrons were changing. In these changes, the nucleus, which contains the protons which dictate which element an atom is, is changing.
