Nuclear Medicine Physics

Audio Overview:

This chapter offers a comprehensive overview of nuclear medicine physics, beginning with basic concepts such as the line of stability, atomic notation, and definitions of different types of nuclei like isotopes, isotones, isobars, and isomers. It then explains mass deficit, nuclear binding energy, balancing nuclear equations, and the principles of radioactive decay, including the calculation of half-life and activity. The text describes common nuclear decay processes, detailing beta decay, electron capture, positron emission, isomeric transitions, and alpha particle emission, and introduces radionuclide generators, explaining how they produce daughter isotopes and the concepts of secular and transient equilibrium. Finally, it addresses radiopharmaceutical dosimetry, outlining how radiation dose is calculated for both charged particles and gamma rays based on factors like effective half-life, and discusses various radiation detectors like gas detectors and scintillation detectors, along with the principles of scintillation cameras, their components, and quality control measures, before briefly touching upon SPECT and PET units and nuclear medicine statistics.
