Attenuation: Photoelectric Effect 2

This is the last post on attenuation methods. Photoelectric effect There are three main steps in photoelectric effect. 1. A high energy incoming x ray photon knocks out an orbital electron (diagrams show K shell electron being knocked out). The energy of the x ray photon must be equal to […]


Attenuation: Compton Scatter

This post is the second method of scatter attenuation. Compton scatter (or Incoherent scatter) There are three main steps in compton scatter. 1. An incoming x ray photon interacts with an outer orbital electron. 2. The incoming x ray photon knocks the orbital electron out of it orbit (becoming a […]


Attenuation: Coherent Scatter

This post is the first of three involving methods of attenuation.  The first two posts will be on types of scatter; coherent scatter and compton scatter.  The last post will be on absorption; photoelectric effect.  These are physics topics and more likely apply to students as they are learning about […]
