Goal(s)

The purpose of this lecture is to provide the students with a description of the main detection principles for charged (electron, proton, alpha) and neutral (photon and neutrons) particles. The course presents the most common devices used in nuclear medicine (both imagery and therapy) with an emphasis on gazeous detectors, semi-conductor devices and scintillators detectors.
For the lab works, the students work in a team of two during 8 hours sessions. Four topics are addressed: alpha/gamma spectroscopies, gamma-gamma coincidences and PET scan.
