The first part of the course deals with the interaction of ionising radiation (IR) with matter, quantities characterising the field of ionising radiation and its impact on a matter, units, and the distribution of absorbed energy in the matter. The rest of the course gives a detailed overview of the properties of detectors of IR, application of detectors, gas detectors, scintillation detectors, detectors for high energy IR, semiconductor detectors, integral dosimetric methods, statistical treatment of data, and limits of detection.

Syllabus of lectures:

1. Interaction of ionising radiation with matter. Heavy charged particles, electrons: inelastic collisions, elastic collisions, breaking radiation emission. Gamma radiation, X-radiation: Compton scattering, pair production. Neutrons: Nuclear reactions.

2. Primary effects from the absorption of ionising radiation: Ion-pairs, excited states, nuclear processes initiation.

3. The radiation conversion of excited states to the ground states - luminescent phenomena. The heat evolution in irradiated matter.

4. The system of dosimetric quantities and their mutual relations. Linear energy transfer, quality factor, absorbed dose, dose equivalent, radiation equilibrium, the relation between the absorbed dose and kerma, depth-dose dependence.

Study Objective:

The course of the detection and dosimetry of the ionizing radiation provides the students with the knowledge of mechanism of the interaction of ionising radiation with matter and the related units, 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.
