parallel plate ionization chamber
Figure 3.7) is defined by the cross-sectional area of the collecting electrode and the separation between the plates. Interactions with the lateral walls of the chamber generate ions primarily at…
of the radionuclide imaging process
Chapter 7. A radionuclide is an unstable isotope of an element that will spontaneously ‘decay’ by the emission of particles and/or electromagnetic radiation. The three most common emissions from radionuclides…
Introduction
1]. Nuclear medicine is the science and clinical application of unsealed radiopharmaceuticals for diagnostic and investigative purposes and this includes imaging. A suitable radionuclide or isotope is combined with a…

Introduction
Chapter 2 described the various processes by which photons interact with matter. These interactions produce charged particles (electrons and possibly positrons) which then travel through matter, losing energy by collision…
of radiation levels
Chapter 3). Ion chambers can be used for such measurements; they have the advantage that they have a relatively uniform response over a wide range of energies and can be…
Introduction
1]. It is relatively cheap, safe, gives real time images and has good soft tissue contrast. As well as anatomical detail, ultrasound can exploit the Doppler effect to give information…
