Objectives and competences

Students get familiar with the health physics principles and basic data that is needed in evaluation of radiation hazard and planning of radiation shielding. Concepts are illustrated with practical examples. This course links with other courses on dosimetry, radiation measurement and other more specific fields.

Intended learning outcomes

Knowledge and understanding:
Obtaining fundamental knowledge of health physics, ionization measurement measurements and radiation safety.

Use in radiological monitoring of environment.

Assessment of danger level in various radiological incidences and planning of mitigation procedures.

Transferable skills:
Ability to collect the data and critically evaluate the level of radiation hazard and recommend adequate mitigation procedures.
