Recommended Prerequisites


Teaching Methods

In the theoretical lectures, the subjects are explained using mainly audiovisual media. In the practical classes students solve problems, followed by discussion, that aim to link the concepts, methods and techniques learned in the theoretical lectures to practical situations.
In practical classes, students carry out computer simulations, in which they apply the knowledge acquired in theoretical lectures. These classes will also include the presentation and discussion of "case studies" in radiation protection and safety.

Learning Outcomes

1) To know i) the fundamental physical radiometric and dosimetric quantities; ii) different type of integral and pulsed dosimeters, as well as instrumentation for personal and environmental monitoring and survey; iii) how to calculate internal and external radiation doses; iv) how to dimension and design screening barriers; v) environmental radiation and radioactive waste management; vi) legislation on safety and radiation protection.
2) To know how to use computational methods for dosimetric calculations and design of radiation protection barriers.
3) Ability to search and use bibliography, organising a consistent set of information regarding the area in study.
4) To know to solve problems involving the calculation of internal and external doses.
