Successful completion of the course "Physical methods of measuring quantities in the environment I" - Course Enrolment Limitations
- The course is also offered to the students of the fields other than those the course is directly associated with.
- fields of study / plans the course is directly associated with
- Environmental Monitoring (programme FU, APFYZB)
- 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
- 1. Non-ionizing and ionizing radiation. Definition of radiation sources (natural, artificial), particle and wave theory of light (radiation), quantum nature of radiation. Fundamentals of field theory. Non-ionizing fields and radiation, electric and magnetic fields - physical quantities, unified theory of electromagnetic field EMF - Maxwell's equations, unified theory of electroweak forces. Energy effects of EMF - Poyting vector. EMF and its spectrum, distribution according to wavelengths (frequencies).
- 2. Optical radiation. Visible light region VIS and peripheral parts of the spectrum, ultraviolet UV and infrared IR radiation. Monochromatic radiation and problems of laser radiation.
- 3. Physiology of vision. Light as a specific part of EMF. The eye and its anatomy. The optic nerve and the perception of light radiation. Terminology and basic units in lighting. Object visibility, contrast, glare, visual fatigue. Radiation polarization. Acute damage to the eye by sources of significant intensity (lasers II, IV class) and sources with a wide spectrum (UV and X-ray).
- 4. Influence of light and lighting on biological systems. Influence on humans and their biological rhythms. Daylight and artificial lighting, vision conditions for various visual tasks. Kruihof diagram of light comfort, light source temperature, color rendering. Requirements for daytime, artificial and mixed workplace lighting. Hygienic minima. Light deficit syndrome SAD.
