Supervisor:
Department of Dosimetry and Application of Ionizing Radiation
Synopsis:

Main part of the course deals with the interactions of ionizing radiation with matter describing the source and the radiation field and its effect in matter. The next section discusses in detail the variables describing the interaction of ionizing radiation (IR) with the matter, the effects of ionizing radiation and microdosimetric variables. The cycle is closed with an overview of the radiation protection system, biological effects of IR and secure management of IR resources in the workplace. Lectures are complemented by an overview of current legislation relating to the use of radiation protection (RP) and IR in practice.

Lectures are supplemented with practical exercises that address the basic models and examples as the calculation of doses and shielding of IR.

Successful students will obtain a certificate required for being registered for an exam leading to receiving a qualification of a Radiation safety officer following the Czech legislation.
