Contents	Electromagnetic radiations. Corpuscular radiations. Structure of the atom. Nuclides and isotopes. Radioactivity. Radiation-matter interactions. X-ray production and attenuation. Attenuation of charged particles.
Reference texts	- Faiz M. Khan, The Physics of Radiation Therapy - Joseph Selman, The Basic Physics of Radiation Therapy - Harold E. Johns and John R. Cunningham, The Physics of Radiology
Educational objectives	Ionizing radiations are the main tool the future TSRMs will work with. The aim of the course is thus to provide the basic knowledge of radiation physics, which will allow the students to understand the working principles of the instruments and devices, with which they will work during both their subsequent studies and their professional life.
Prerequisites
Teaching methods	Face-to-face lectures.
Other information
Learning verification modality	The student can choose between two alternative examination methods: a) a written exemption test, taken shortly after the end of the lectures of the radiation physics module; b) an oral examination, after the end of the semester, on the official exam dates. Given the propedeuticity of the radiation physics module, the exemption test method (a) is strongly encouraged.
