Radiation protection and nuclear measurements [ LBNEN2002 ]


6.0 crédits ECTS

Lieu de l'activité Louvain-la-Neuve
Préalables

It is assumed that the students have a good background in basic physics as is usually part of the curriculum of the first two years of engineering, physics or mathematics. More in particular they should be familiar with classical theory of electromagnetism and classical mechanics.
An introductory level knowledge to electronics and circuit theory is also assumed.
Students should preferably also have an elementary knowledge of special relativity.
The course contains a short reminder of this subject, but this is probably difficult to comprehend for students who never had an introduction to special relativity. A basic knowledge of quantum mechanics is helpful but not essential.

Thèmes abordés
  • Introduction to subatomic physics
  • Reminder on special relativity
  • Reminder on probability theory
  • Interactions of charged particles in matter
  • Interactions of X and gamma rays in matter

  • Introduction to Accelerators
  • Accelerators for accelerator driven systems
  • Detectors based on ionisation in gases
  • Detectors based on ionisation in semiconductors
  • Detectors based on scintillation

Acquis
d'apprentissage

The aim of the course is:

  • to introduce the student to the physical principles of the interaction of subatomic particles and high-energy radiation with matter
  • to learn how to apply the concepts of external/internal radiation dosimetry
  • to introduce the student to the biologic effects of ionising radiation
  • to learn how to apply dispersion models
  • to be able to calculate the effects of shielding materials
  • to know the concepts and legislation of radiation protection
  • to give an overview of the different methods for detecting and quantifying the presence of such particles and radiation
  • to give an introduction to the principles of particle acceleration
