The advancement in science and technology has resulted in the invention and widespread usage of many electrical devices in the daily lives of humans. The exponential use of modern electronic facilities has increased electromagnetic field exposure in the current population. Therefore, the presented article deals with designing, constructing, and testing a new applicator system developed for cells electromagnetic biocompatibility studies. The applicator system is intended for studying the non-thermal impacts of low-frequency magnetic field on cell cultures growth. Main attention is focused on increasing the capacity of the applicator and effectivity of the experiments. The key idea is to reach high level of the magnetic field homogeneity in an area of interest and the temperature stability during the biocompatibility studies. The applicator system is designed based on numerical simulations and its construction, measurements, and properties evaluation are also reported for proving the applicator’s functionality. The new applicator allows performing five parallel experiments at the same time under the same conditions. The simulation together with the experimental results confirm that the magnetic field homogeneity reaches 99% in the area of interest and the maximum temperature instability is lower than 2% during the experiments. The effectiveness of new applicator is tested and proved during preliminary experiments with Saccharomyces Cerevisiae cells. The observed effects of MF exposure represent maximal stimulation of 74% and maximal inhibition of 49%. The reason why MF with the same parameters induces inhibition in one sample and stimulation in the other will be the subject of further research.

The increasing evidence regarding biological effects of exposure to an extremely low frequency magnetic field is of utmost interest not only to the scientific community, but also to legislative bodies and the public. However, the research in this field is full of controversial and inconsistent results, originated from a lack of widely acceptable physical mechanisms that could sufficiently describe the principle of such a field’s action. This experimental study addresses and points to possible sources of ambiguities via investigation of the ion parametric resonance mechanism at 50 Hz frequency. The chosen methodology incorporates exposure of the Saccharomyces cerevisiae yeast strain based on an established exposure protocol with special attention to the measurement of an applied time-varying magnetic field corresponding to the ion parametric resonance requirements. Subsequently, the differences in cell growth as a reaction to changes in magnetic flux density are evaluated and statistically analyzed. It is found that fluctuations in the magnetic field within the exposure setup need to be addressed properly, since this could have an impact on replication of the experiments and reliability of the results. Furthermore, comparison of two independently performed sets of 10 experiments showed statistically significant effects even in conditions that did not fulfill the requirements of the resonance theory, putting the validity and practical application of the ion parametric resonance model into question.

The electromagnetic field is an inseparable part of the contemporary world. Ubiquity of low and extremely low-frequency electromagnetic field produced by the distribution of household electricity has attracted special attention. A number of dosimetric analyzes of the electromagnetic field realized by various researchers have detected high exposure values in the different microenvironment of human life. Other studies report potential associations between exposure to low and extremely low-frequency electromagnetic field and various health outcomes. This paper shows an overview of the electromagnetic situation in our life microenvironments and her possible health impacts.

The main goal of the paper is the measurement of electromagnetic field distribution inside the two cars with modern embedded wireless technologies. Measurement was performed in standard urban environment in the cars with mobile phone Bluetooth connection for two cases by each car, without usage of the phone and receiving the call. Results of the measurements show, that in modern cars with more wireless technologies are many high frequency sources of electromagnetic fields. Although the values of these measured variables do not exceed the limit levels, it depends on the current state of the organism and the time of exposure.

Freedom is needed in family planning and in the decision on how many children the couple will have, not to be influenced by a third person, political situations, or religious conviction. There is a need for information, education, and communication about possibilities in natural family planning, in order to be able to choose the right way, because there are many options even without side effects. Nowadays, we can add to these traditional possibilities of natural family planning also information technologies and electronic devices, which are increasingly available to a large portion of the population. Their reliability, with correct usage, is comparable to the barrier methods and in some cases to hormonal contraceptive methods. Next development of these devices can more increase their reliability. Of course, the active approach of users is needed.
