Learning Outcomes

The aim of the course is:

  • to know the basic quantities and units used in radiation protection
  • to learn how to apply the concepts of external/internal radiation dosimetry
  • to introduce the student to the biologic effects of ionising radiation
  • to be able to calculate the effects of shielding materials
  • to know the concepts and legislation of radiation protection

Grading and examination

Written examination accounts for 80% in the total mark:
  • exercise part: "open book" (50%)
  • theoretical part "closed book" (50%)

Lab sessions are compulsory. Report of lab sessions account for 20% in the total mark. Lab sessions can not be repeated in second sessions.
