The first part of the course deals with the definitions, properties, and application of the detectors of ionising radiation (IR). In the second part, a detailed overview of the gas detectors, scintillation detectors, detectors for high energy IR, semiconductor detectors, and integrating solid state detectors is given. The last part of the course reviews the principles of the statistical treatment of data, and limits of detection.


Knowledge of physics on the level of a completed basic university course. Basic knowledge of the structure of atoms and nuclei. Knowledge of the mechanisms of interaction of ionising radiation (IR) with matter and of principles of IR dosimetry.

Study Objective:

The course of the detection of ionizing radiation provides the students with the knowledge of the principles of the function of various types of detectors, and basics of the treatment of measured data and limits following from the statistical character of this data. The students will acquire competence to select the type of detector appropriate for their respective application(s), comprehend the results of the measurement of ionising radiation, and correctly interpret their statistical relevance.
