The study published by Dipl.-Biol. Isabel Wilke in 2018 is a comprehensive systematic review that examines the biological and pathological effects of 2.45 GHz radiation – a frequency commonly used in Wi-Fi networks. This meta-study analyzed more than 100 scientific papers dealing with the effects of this radiation on cells, fertility, brain and behavior. For the analysis, the author drew on studies from renowned databases such as LIVIVO (ZBMED) and PubMed, taking into account both experimental and epidemiological studies.
The results of the investigation show that the majority of the studies analyzed found significant changes in irradiated samples compared to non-irradiated control groups. It is striking that these effects already occurred at radiation intensities below the limits recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The documented effects included impaired fertility, such as reduced sperm quality and motility. Effects on the brain were also observed, including changes in brain activity, cognitive impairment and negative effects on learning and memory. Further studies have shown health effects on organs such as the heart, liver and thyroid as well as on gene expression, the cell cycle and cell membranes. Bacteria and plants also showed signs of changes caused by 2.45 GHz radiation. Oxidative stress, which can cause cellular damage, has been identified as a possible mechanism in many studies.
Based on these findings, the author concludes that the current exposure limits and SAR values (Specific Absorption Rate) are not sufficient to protect the body from the health risks of 2.45 GHz radiation. It therefore recommends minimizing radiation exposure in everyday life and preferably using wired alternatives. This is particularly important in sensitive areas such as bedrooms, workplaces, classrooms, public transport and hospitals. For educational institutions, the study expressly advises against the use of WLAN in order to avoid negative effects on learning, attention and behavior in children and young people.
The study emphasizes that despite the extensive data available, scientific uncertainties remain and stresses the importance of further research in this area. The full review has been published in the journal “umwelt – medizin – gesellschaft” and can be accessed via the publisher Diagnose Funk. While the study provides clear evidence of potential health risks, the debate about the effects of WLAN radiation remains controversial in the scientific community.
