Original Abstract

It was confirmed that the concentration of light air ions has a positive influence on human health. For an objective appraisal of the influence of synthetic sources of negative air ions, a comparison with the natural environment is necessary. The concentration of air ions and their mobility spectrum can be determined by the help of an aspiration condenser. Based on measurements using the condenser, the spectrum mobility can be calculated from the measured saturation characteristics. In the report, different options suggesting the most advantageous approach to the approximation of saturation characteristics are discussed from the point of view of minimal numeric error. The saturation characteristic approximations are made in Matlab. Using this method, the comparison of air ion spectra in different types of environment will be done. These types include a natural forest on the one hand and the production of a synthetic source of negative air ions on the other.
