There are a lot of photon interactions throughout the radiologic field. These are produced when matter and excited electrons interact with each other at the same level. The photons are able to penetrate through matter without a big interaction due to the energy being absorbed in matter. The photons in this interaction are the x-ray and gamma photons. Their lives are ended when they give off their energy to an electron in need. This interaction along with the other interactions are very important
