Course objectives
The course will provide students with basic physical knowledge in the field of physical quantities determining the environment and measuring methods and principles of measurement applicable to their measurement. This part II includes physical theory, physical methods and measurement principles that are relevant to the issue of measuring non-ionizing radiation. Emphasis is placed on the physical nature of the problem and the application of physical theory to the measurement of non-ionizing radiation and protection against the adverse effects of this radiation.
Learning outcomes
The student will be able to define a physical quantity characterizing a given type of EM radiation, describe the measuring method and explain the physical nature of the problem.
Syllabus
