Radiological Protection and Dosimetry

Code 13514
Year 1
Semester S1
ECTS Credits 6
Workload TP(60H)
Scientific area Biomedical Sciences
Entry requirements Do not exist.
Mode of delivery Face-to-face Professor-centered teaching, with active participation of students.
Work placements Not applicable.
Learning outcomes Introduce the main topics of dosimetry and radiation protection, as well as identify and relate the biological effects of ionizing radiation.

At the end of the UC the student should be able to:
1. Analyze and discuss coherently the subjects taught, putting in evidence the
basic theoretical principles and experimental evidence;
2. Interpret, solve and discuss problems, on the subjects taught, of high and
intermediate level;
3. Realize and discuss, in group, pratical work.

Teaching Methodologies and Assessment Criteria Theoretical-practical classes (TP) with oral presentation of the topics of the subjects, using audiovisual means, complemented with a tutorial regime associated with self-learning and accompanied study by the students. Students will make use of software dedicated to radiation interaction with matter and will be asked to present and discuss some of the topics covered.

Final evaluation of the Curricular Unit will consist of two components, one punctual and the other continuous:
1. Punctual evaluation will be carried out through two written tests (with a weight of 60%)
2. Continuous evaluation (with a weight of 40%)

Language Portuguese. Tutorial support is available in English.
