The aim of the project is to acquire a sound basis in radiation protection and the safety of radiation sources at the basic level. The project also aims to provide the necessary practical skills and basic tools for those who is going to work in the field of radiation protection and the safe use of radiation sources in their countries. The project consists of a series of laboratory works on basic nuclear physics, interaction of radiation with matter, dosimetry and shielding.
