Learning outcomes

The student acquires the physical bases of the methods used in nuclear medicine, radiation protection, the interaction of radiation with matter (in particular also the range and danger of beta and alpha particles). Recalls on the interaction of photons. Review of: atom structure: Rutherford model; nucleons and electrons; Mass number and atomic number; isotopes. Symbology of nuclides. The student knows the energies used in radiotherapy, acquires knowledge on radiation protection in radiotherapy, dosimetry in radiotherapy, phases of the radiotherapy process and planning techniques. Physics of IORT and Proton therapy.

Teaching methods

- Frontal teaching, use of audiovisuals and, where possible, demonstration of the equipment.

-Since the subject is undoubtedly complex, the teacher will seek contact and dialogue with the students, not to judge, but rather to facilitate an active approach and understanding of the topics.

In consideration of the types of activities and teaching methods adopted, the attendance of this training activity requires the carrying out for all students of modules 1 and 2 in e-learning mode [https://www.unibo.it/it/servizi-e-opportunita/salute-e-assistenza/salute-e-sicurezza/sicurezza-e-salute-nei-luoghi-di-studio-e-tirocinio] and the participation in module 3 of specific training on safety and health in the places of study. Information on dates and methods of attendance of module 3 can be consulted in the specific section of the degree program website.

Assessment methods

Oral interview during which the student is invited to discuss the topics covered during the lessons, which are also found in the texts recommended for study and in the teaching material presented and discussed during the lessons.

The interview will be assessed on the basis of the following parameters:

- knowledge, mastery and in-depth analysis of the contents
- critical and expository skills
- technical and scientific terminological correctness
- professionalism and ability to exhibit

Teaching tools

Power Point slides, Java Applets, movies.

Where possible, demonstration of tools and equipment.
