Health effects of ionizing and non-ionizing radiation
Gottvald, Martin ; Neoral, Jiří (referee) ; Bača, Petr (advisor)
This diploma thesis deals with electromagnetic radiation in its frequency spectrum. It also divides radiation into ionizing and non-ionizing. The principle of its effects and possible health problems from radiation exposure are also described. Hygienic limits – the maximum allowable and reference values of non-ionizing radiation are analysed too. The thesis should prove that the things of everyday need do not threaten the lives of human beings and are in compliance with the regulation No. 1/2008 Sb. on Health Protection Against Non-Ionizing Radiation. Measurement of low-frequency part is carried out with the cooperation of The National Institute of Public Health. Measurement of high-frequency part was carried out in 3 flats. The aim of this measurement was to find out the change of power density with the moving in a flat and the influence of the barriers (in this case walls).

Measurement of the respiratory sounds
Gottvald, Martin ; Rychtárik, Milan (referee) ; Kolář, Radim (advisor)
Respiratory sounds measurment This thesis deals with respiratory sounds analysis and measurment using digitalizing measuring cards and LabView environment. The anatomy of respiratory system is described, including each of its fractions and disturbances related to the respiratory system. The design of respiratory sounds amplifier is described, but wasn´t used considering the interferences of measured signal caused by the power-line frequency which results in substantial distortions. That's why, the previously recorded respiratory sounds were used for analysis in Matlab. The measuring program was designed in LabView, which alows signal recording from using acquisition card input and further processing.
