Objectives of the Course
It is aimed to provide an understanding of the sources of background-environmental radioactivity and cosmic rays and methods to suppress their effects. The basic principles of the detectors used are explained, systems with each of these detectors are described and their characteristic background effects discussed. The most important application areas of the low-level technique are described.
