* Load is given in academic hour (1 academic hour = 45 minutes)
The goal of this module is adopting the basic knowledge about the usage of ionizing radiation in diagnostics radiology and radiotherapy. Also, students should understand and be able to do the measurements of basic dosimetry quantities used. The models used for determining the risk of ionizing radiation exposure will be introduced as well as recommendations for safe use of ionizing radiation from the international regulatory bodies. Learning outcomes should be:
* To adopt the basics on diagnostic and therapeutic methods used in medicine based on ionizing radiation application.
* To describe ionizing radiation generators used in medicine.
* To understand the role and duties of a medical physicist.
* To understand the physical quantities used in biological radiation effects measurement.
* To understand the interaction of tissues and different types of radiation that is fundamental for all diagnostic and therapeutic methods in medicine.
* To apply the principles of radiation protection in procedures developed to ensure the safe usage of ionizing radiation. To understand the importance of these procedures for worker's and patient's safety.
* To apply the acquired knowledge in medical physics in practice. To continue to expand the knowledge.
