Course description

The study of static and dynamic properties of nuclei constitutes a first essential step in the comprehension and exploitation of Nuclear Science. Starting from the experimental evidence of radioactivity, the course will explore:

  • the physical and the random nature of radioactive decay and nuclear reactions;
  • the experimental methods and detector technologies to measure radiations produced by nuclear processes.

To better explore the topic, we will enter in POLIMI Labs to look at the working principles of the detectors employed in gamma-ray spectrometry. Also, we will see how nuclear reactions can be exploited to detect the presence of neutrons and to measure their energy.
Finally, we will see the main procedures used in radiochemistry to perform destructive analysis, useful When nuclei are hard to measure.

Total workload of the course: 25 hours

This MOOC is provided by Politecnico di Milano.

Information about fees and access to materials

You can access the course absolutely free of charge and completely online.

Course materials will remain available to all enrolled users after the end of the current edition, so they can return to content later. The current course edition will be followed by a new one just after its end.

Learning schedule

The course is structured in 4 main weeks.

  • Week 1 – Intro to nuclear processes
  • Week 2 – Principles of radiation detection
  • Week 3 – Hard-to-Measure radionuclides
  • Week 4 – Welcome to nuclear Labs

The weeks have different lessons within them, consisting of videos, quizzes, completed by additional materials and resources. These last allow you to reach a level of detail greater in some topics of your interest.

In particular, Week 1 will specifically address radioactivity in the time domain, radioactive decays and related properties, nuclear reactions and cross section.

In Week 2 will focus on both Gamma-matter interaction and detectors, and Neutron sources and detectors.

Week 3 will focus on Radiological characterization which is of paramount importance for nuclear safeguards and specifically on how to determine Hard-to-Measure radionuclides.

Week 4 opens the door to some Laboratories of Politecnico di Milano which deals with nuclear measurements, gamma spectrometry, Radiochemistry and Radiation Chemistry.

Prerequisites

As prerequisite it is recommended to have some basic knowledge of chemistry and physics.

Activities

Over and above consulting the content, in the form of videos and other web-based resources, you will have the opportunity to discuss course topics and to share ideas with your peers in the Forum of this MOOC.

Throughout each module, you will also find some “Self assessment quizzes”. Self assessment quizzes are not graded: they are meant to support the consolidation of the knowledge acquired following the previous video and to help you understand which are the main takeaway.

Assessment

The final grade for the course is based on the results from your responses to the quiz you’ll find in week 5 (which is devoted to the Final Quiz).
You will successfully complete the course if you reach 60% (or more) of the total score of the Final Quiz by the end of the edition.

Certificate of Accomplishment

The Certificate of Accomplishment will be released to anyone who successfully completed the course by answering correctly to at least 60% of the questions of the Final Quiz (week 5). You will be able to download the Certificate of Accomplishment directly on the website.

Once you have successfully passed the course, you can request the Certificate of Accomplishment without waiting for the end of the edition.

The Certificate of Accomplishment does not confer any academic credit, grade or degree.
