Objectives
Programme
1 Basics of electromagnetic environment protection. Relationship between electromagnetic compatibility and biological effects. Review of non-ionizing radion and the role of the frequency
2 Interaction between electromagnetic fields and living organ: induced field, displacement current and thermal effect. The frequency dependence.
3 Physiological basics. The cell membrane and its electrical model. Development of action potential. Electric signals in the living organism. Electrical processes in muscles, heart and receptors.
4 Health effects of electric current. Consequences of electric shock at low and high voltages. Biological thresholds. The role of the current, frequency and time in health effects. Protection against electric shock, in buildings, especially healthcare buildings.
5 Effects of current impulses. Electrostatic discharges (ESD), charge accumulation and their properties. Protection against the negative effects of ESDs. Health effects of ESDs, energy of discharges.
6 Development of lightning strike, charge accumulation processes. The lightning current. Direct and indirect lightning strike, typical injuries. Differences between the effects of power frequency shock and lightning strike.
7 Electric and magnetic fields in the proximity of high and medium voltage power lines and parameter dependence. Fields generated by the low voltage power system, household and industrial equipment. Protection against low frequency fields.
8 Health effects of low frequency electric and magnetic fields. Main coupling mechanisms. Results of cellular, animal studies.
9 Basics of epidemiology. Epidemiological studies of low frequency fields. Results and criticism.
10 Health effects of radiofrequency fields, interaction mechanisms, thermal effects, limit values and frequency dependence. Results of cellular, animal and epidemiological studies.
11 Radiation and health effects of mobile communication and other information and communication technology devices.
12 International standards and regulations.
13 Measurement of electromagnetic fields. Theory and application.
14 Laboratory demonstration: Live line maintenance
The subject deals with a special area of electromagnetic environmental protection, namely the biological effects of electromagnetic fields, focusing on the possible adverse effects of non-ionizing radiation on human body. The sources of electromagnetic fields and the fields of electrical equipment are also introduced. The consequences of electrostatic discharges and lightning impulses are reviewed and compared with typical injuries of electric shock. The main purpose is that the students will be familiar with problems and regulations of electromagnetic environment protection and biological effects of electromagnetic fields, moreover they will be capable of handling the critical issues of this field.
