Prerequisites

The following BNEN course is a prerequisite:

Introduction to Nuclear Physics and Measurements

It is also 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.

Aims

At the end of this learning unit, the student is able to :

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
