The aim of the course is that the participants acquire knowledge and understand the problems connected with Health Physics and Radiation Protection, subjects with a strong interdisciplinary content, whose understanding can make a contribution to a better quality of the life, of the environment, for health and safety in the workplace, subjecys that are of primary interest in the life sciences field. The aim is to make it clear that since the beginning of the twentieth century numerous discoveries and new applications have followed one after another in the various sectors of Physics, significantly leading to a widening of knowledge also in disciplines, not necessarily related to Physics, but which contribute more than any other to improving the quality of life. These include the applications of ionizing radiation, starting from the discovery of radioactivity and X-rays, up to the medical applications of the use of radionuclides for diagnostics and metabolic radiotherapy and of NMR imaging techniques. For this purpose, the conceptual bases of Health Physics are provided, explaining and deciphering the characterizing concepts of this discipline in the specific operational aspects of the subject itself. Health Physics, in addition to covering aspects of operational radiation protection, addresses the development of new analytical and dosimetric techniques and wider issues, such as support and aid to decision making, in relation to the assessment of risks, the drafting of guidelines in the management of problems that may involve radioecology, waste management, food safety, energy production, use of diagnostic or therapeutic techniques, use of radiopharmaceuticals, toxicology, the use of alternative techniques in the control of industrial processes.

Prerequisites for admission
1. Nuclear and Subnuclear Physics Course; 2. Chemistry Course; 3. Course of Interaction and Detection of Nuclear Radiation.
The didactic method adopted provides frontal lessons. The course is enriched with some hours of lessons in English provided by guest foreign professors who collaborate with the research group, on the topics of environmental radioactive contamination and on the part of nuclear reactors. The guided visit to the Applied Nuclear Energy Laboratory - LENA of the University of Pavia is also carried out, as a practical exercise on the topics of operational radiation protection, presented during the course.

Assessment methods and Criteria
The exam consists of an interview lasting an average of about an hour and includes an oral discussion on the topics covered in the course, aimed at ascertaining the level of understanding achieved in relation to the subject matter. The exam starts from notional questions and develops in such a way that the candidate demonstrates the real mastery of the subject by discussing and critically linking all the topics covered in the course: it starts from a concrete case of use of ionizing radiation and the student must be able to solve it by putting everything presented in the course into play.
