Radiation Physics and Radiation Protection

Atomic and Nuclear Physics (1st year IMR)

2 hours of theoretical class per week, where the professor exposes the subject’s programmatic content, using the illustration of the physical concepts presented with examples.

1 hour of theoretical-practical class per week, where students (separated into shifts with a maximum of 20 students) discuss application exercises formulated with the aim of clarifying and relate the subjects discussed to the specificity of Medical Imaging and Radiotherapy.
