Abstract

An ever-increasing use of wireless devices over the last decades has forced scientists to clarify their impact on living systems. Since prenatal development is highly sensitive to numerous noxious agents, including radiation, we focused on the assessment of potential adverse effects of microwave radiation (MR) on testicular development. Pregnant Wistar albino rats (3 months old, weighing 282±8 g) were exposed to pulsed MR at a frequency of 2.45 GHz, mean power density of 2.8 mW/cm², and a specific absorption rate of 1.82 W/kg for 2 hours/day throughout pregnancy. Male offspring were no longer exposed to MR following birth. Samples of biological material were collected after reaching adulthood (75 days). In utero MR exposure caused degenerative changes in the testicular parenchyma of adult rats. The shape of the seminiferous tubules was irregular, germ cells were degenerated and often desquamated. The diameters of the seminiferous tubules and the height of the germinal epithelium were significantly decreased (both at ∗∗p<0.01), while the interstitial space was significantly increased (∗∗p<0.01) when compared to the controls. In the group of rats prenatally exposed to MR, the somatic and germ cells were rich in vacuoles and their organelles were often altered. Necrotizing cells were more frequent and empty spaces between Sertoli cells and germ cells were observed. The Leydig cells contained more lipid droplets. An increased Fluoro Jade – C and superoxide dismutase 2 positivity was detected in the rats exposed to MR. Our results confirmed adverse effects of MR on testicular development.

This review documents more than 100 studies that detect health risks of the carrier frequency 2.45 GHz and the pulsed variant WLAN/Wi-Fi.  The study results regarding the risks not only advises the adoption of a precautionary policy, but it includes a danger warning:  No WLAN/Wi-fi at schools!

The physicist Dr. Klaus Scheler wrote about this review: “The review was based on an intensive worldwide search and analysis of over 100 studies documenting the harmful effects of 2.45 GHz and WLAN/Wi-Fi on the following endpoints: Reproductive and fertility (18 studies and 8 Reviews), brain and brain development (12 studies), nervous system and behavior (22 studies), DNA damage and tumor risk (29 studies), cell membrane, oxidative cell stress (41 studies and 1 review), organs (heart, liver, thyroid, 7 Studies), bacteria and plants (2 studies each). It is noteworthy that most of the studies document damage, even at power flux densities and SAR values ​​well below the limits, sometimes even at very low intensities (from whole body SAR = 0 , 1414 mW / kg, current limit: 80 mW / kg).

The review is not limited to a list of studies and their results. The reader also learns how to biologically classify the observed effects, how scientists, physicians and organizations have already responded and what conclusions need to be drawn.

The review by Isabel Wilke makes a valuable contribution to education about the health risks of mobile telephony and especially WLAN/WiFi.  The explosive scientific evidence for the pathological effects of WLAN/Wi-Fi are thus accessible and comprehensible for everyone.

2.45 GHz on cells, fertility, brain and behavior. Wilke_Review_WLAN_180220_Leseprobe

Conclusions: Due to the extensive research situation and the negative health effects, which are found in the majority of studies, it is recommended to take measures to reduce radiation exposure. Wired solutions should be preferred.

The applicable limit and SAR values ​​do not protect against the health risks of WLAN/Wi-Fi radiation. The negative
effects on learning, attentiveness and behavior constitute a renunciation by educational institutions of all ages
regarding Wi-Fi applications. Due to the cytotoxic effects, WLAN/Wi-Fi usage as a technology in hospitals and for
tele-medicine is not suitable. Wi-Fi should not be used in bedrooms, workplaces, lounges, sick rooms,
lecture halls, classrooms and public transport. The potential dangers of WLAN/Wi-Fi radiation
could be circumvented by testing alternative transmission techniques with other frequency bands,
like optical VLC / LiFi technology (Visible Light Communication). If you are unable to avoid WLAN/Wi-Fi,then as a temporary solution, (according to the ALARA principle): Use disconnectable and performance-controlled wireless internet access.
