5 Questions
What is the result of the annihilation reaction between the positron and the electron?
Formation of two high-energy photons
What particle is converted to a neutron during the β+ decay process?
Proton
What happens to the positron when it travels a short distance in the body?
It annihilates with an electron
What is the energy of each photon produced during the annihilation reaction?
511 keV
What term is used to describe the line along which the radioactivity is localized between two detectors detecting photons in opposite directions?
Line of response
Learn about the process of positron emission tomography (PET) where a positron-emitting isotope undergoes β+ decay in the body, resulting in the formation of high-energy photons. Understand how PET scans work and the principles behind the detection of these photons.
