KNOWLEDGE AND UNDERSTANDING
After the course, students are expected to have a good knowledge and understanding of key concepts and fundamental principles on which radiation protection protocols, both for the general public and radiation workers, are based. Additionally, students are expected to be familiar with the most widely used radiation protection instrumentation.
APPLYING KNOWLEDGE AND UNDERSTANDING
After the course, the student should be able to:
- perform gamma spectroscopy measurements to assess the radioactivity of environmental samples in standard geometries.
- correctly use ionization chambers or dose rate meters for radiation protection assessments
- be able to operate an X-ray tube, understanding the effect of voltage and current on the produced radiation.
MAKING JUDGEMENTS
In addition to the knowledge of concepts, students should demonstrate how to apply the concepts in the analysis of practical examples. More specifically, students should be able to read reports on environmental dosimetry and related to the use of radiological equipment, and understand potential radiation protection impacts on workers and the general public.
COMMUNICATION SKILLS
The oral exam aims to evaluate the ability of the student to use effectively and with adequate terminology the concepts covered during the course. Laboratory reports submitted throughout the course are aimed at the evaluation of clarity and conciseness in written text.
LEARNING SKILLS
After the course, students are expected to be able to autonomously go into detail on radiation protection topics and apply the acquired knowledge in more advanced courses.
Basic courses of calculus and general physics.
Concepts of radiation dose and definition of dosimetric and radiation protection quantities.
Natural radioactivity and background radiation, with a dedicated focus on the Radon gas issue.
Radiation protection principles and international guidelines for radiation exposure limitation for the general population and radiation workers.
Detectors and measurement techniques of the radioactivity in environmental samples and laboratory radioactive sources.
Dose rate meters and dosimeters for radiation protection assessment in the working environment.
Introduction to the working principles of X-ray tubes and related radiation protection
Introduction to radiation protection concepts in the field of non-ionizing radiation and related instrumentation.
Laboratory activities include:
- Gamma spectrometry
- Determination of shielding power of different materials and irradiation geometries.\
- Comparison between different dose rate meters
- Estimation of X-ray-generated scattered radiation
- Construction of a simple proportional counter
- Simulation of a radiation protection preliminary assessment
- Outdoor measurement of electromagnetic fields

Lessons, group laboratory activities, seminars by professionals in the field of radiation protection.
The assessment will be performed in the form of an oral exam.
Each group will be required to produce a report for each laboratory experience. The reports should be submitted preferably by the end of the course and at least one week before the oral exam. The oral exam will begin with a discussion of one or more of the reports presented by the candidate. The candidate must demonstrate the ability to describe the methods, discuss the results presented, and correlate them, with appropriate language, to the theoretical concepts learned during the course.
The oral exam score will be expressed in thirtieths based on the following evaluation grid:
18-24: Sufficient or fair knowledge of the subject, adequate command of technical language
25-27: Good or excellent knowledge of the subject matter, mastery of technical language, essential ability to connect the topics covered during the course
28-30 and laude: Excellent knowledge of the subject matter and technical language, autonomous critical thinking skills, ability to apply acquired knowledge to real-world scenarios.
The exam will last approximately 45 minutes.
