Learning objectives

This corse about Heath Physics is one part of the main course. It wants to give a background to undergraduate students about health and environmental physics related to the ionising radiations with aim to use the knowledge and the acquired understanding to identify a risk related to ionizing radiation or its uses. These results can be achieved with the understanding of many applications of ionising radiations used in diagnosis and therapy .

Course unit content

The first part of lectures is related to the definition of ionizing radiations with particular reference to the production of X-rays and to the production of radiation emitted during radioactive decays.
The second part of the course is devoted to the discussion of the ionizing radiation interaction with matter. In particular, it will be explained the interactions of X-ray, gamma photons, heavy charged particles, light charged particles and neutrons with matter. The third part of the course covers applications with particular reference to biomedical and industrial diagnostic techniques.

Teaching methods

The course will be held through lectures to Students either in the classroom (“in presenza”) or in synchronous-streaming (“in telepresenza”) on the Teams platform. During class students are engage through the use of spreadsheets, tools and applets.
Therefore, the opportunity of Student/Teacher interaction will be preserved both face to face and remotely, by the simultaneous use of the Teams platform.
Lectures will be supported by slide presentations, which will be available to students on the Elly platform (

Assessment methods and criteria

The assessment of the achievement of course aims is obteined with an oral exam. In case of the persistence of the health emergency, the exams will be conducted remotely, as follows:
remote oral questions, through the Teams platform (guide
Students with SLD / BSE must first contact Le Eli-che: support for students with disabilities, D.S.A., B.E.S. (
By means of questions regarding the contents of the course, it will be ascertained whether the student has determined the objective of knowledge and understanding of the contents. By means of questions regarding applications in the healthcare and industrial sectors, it will be determined whether the student has achieved the objective of applying the acquired knowledge.
