Learning outcomes

• Knowledge and understanding

At the end of the course the student will have to know the fundamental principles of radiation physics, both ionizing and non-ionizing, as well as the main methods of radiation detection and the foundations on which the methods and techniques of radioprotection are based.

• Ability to apply knowledge and understanding

The student should be able to apply the concepts learned during the course, in particular to evaluate at least summarily, even in quantitative terms and on the basis of experimental data, the danger level in environmental and working situations involving the risk of radiation, both ionizing and non-ionizing.

• Transversal Skills

The acquired competences can be applied in the common laboratory practice, also in the industrial field, in the case a radiation risk is foreseen.

Program

The course corresponds to 1 credit, for a total of 10 hours of frontal lessons. The program consists of the following topics:

• Introduction: Wave-particle dualism, electromagnetic and particle radiation

• Ionizing radiation: Natural sources (cosmic rays, natural radioactivity, radon)

• Atomic nucleus, radioactive decay, law of decay, mean life.

• Interactions of ionizing radiation with matter; Biological effects of ionizing radiation

• Dosimetric quantities, particle detectors and dosimeters.

• Basic principles of radiation protection and limits by law for doses.

• Nuclear energy: Fission and fusion, principle of operation of atomic bomb and fission reactor; Nuclear accidents, INES scale.

• Non-ionizing radiation: microwaves and their dangers. Specific absorption rate (SAR) and limits by law.

Development of the examination

Way of learning evaluation

Written test (multi-response quiz).

Learning Evaluation Criteria

The written test consists of 15 multi-response questions, about the different topics provided in the program. Questions will be formulated in such a way that it is possible to verify that the knowledge acquired is sufficiently relevant to all parts of the programme.

Learning Measurement Criteria

The learning will be evaluated positively if an exact answer to at least 3/5 of the questions is provided, without any other errors.

Criteria for attributing the final vote

The vote is expressed in thirtieths. Each of the 15 questions, in case of an exact answer, are assigned 2 points, for a maximum vote of 30/30. 0 points are assigned to ungiven answers, -0.1 points, to wrong ones.
