5G - Medical study situation

Medical studies on the 5G radiation emitted by mobile phone antennas worldwide are becoming increasingly important thanks to well-founded publications.

Study design

A study design that meets the gold standard in clinical research must be double-blind and randomized in a controlled manner.

Double-blinded means that neither the patient nor the practitioner knows whether a Placebo (usually NaCl - neither active substances nor excipients or additives may be included) or the real medication is administered.

In a randomized study, the study participants are randomly assigned to one of the two existing groups: the experimental group, also known as the verum group, or the control group, also known as the placebo group.
In this way, systemic differences are largely minimized, thus ensuring comparability between the two groups.

One controlled A randomized study requires the comparison of data between the control and experimental groups.
When recruiting study participants, the aim is to obtain a sufficiently large and representative sample.

As already mentioned in the article EHS – Electrohypersensitivity the effects of high-frequency 5G radiation (depending on radiation power and radiation dose) can rarely be diagnosed in a sufficiently medically reproducible manner. People experience latent, but for them quite manifest, restrictions of a health nature.
Medically, they are usually dismissed as malingerers, regarded as mentally unstable, rarely taken seriously, shunted back and forth between medical disciplines and ultimately treated purely symptomatically.
The cause of 5G radiation, on the other hand, is only considered in a few cases, and even more rarely actually accepted by doctors and authorities.

Limits

Limits are adjusted arbitrarily. However, they are hardly ever defined on the basis of knowledge, but rather presumably measured to serve economic aspects. Criticism of 5G exposure is seen as undesirable rather than constructively helpful in the decision-making process.

As Conrad Röntgen when he discovered the X-ray radiation named after him, he knew nothing about its possible harmful effects.

Initial exposure limits were therefore more or less based on estimates. Over time, they were constantly adjusted because it was recognized that the damage can be severe, as the effect of radiation on the organism is additive.

This ultimately led to the introduction of the X-ray passport. These record the doses of X-ray examinations (X-ray and CT) and thus serve as a criterion for further radiation exposure.

State votes

The German Federal Office for Radiation Protection (BfS) points out, in accordance with existing scientific uncertainties, that legal limits should be supplemented by precautionary measures, such as minimizing exposure, providing comprehensive information to the public and further research. Here are the sources of the BfS regarding the recommended precautionary measures with regard to. High frequency fields.and Low frequency fields.

That too Swiss Federal Office for the Environment (FOEN) in his article Electrosmog: the most important facts in brief, know that various studies provide evidence of biological effects at low radiation exposure levels below the limit values. Weak high-frequency radiation can change brain waves and influence blood flow and metabolism in the brain.

Current study

A very recent study "5G radio-frequency-electromagnetic-field effects on the human sleep electroencephalogram: A randomized controlled study in CACNA1C genotyped volunteers", published in the NeuroImage Vol. 317 on 18.06.2024, sheds light on the influence of 5G radiation on the sleep encephalogram.

The authors Georgia Sousouri¹, Corinne Eicher^1,2, Rachele Maria D'Angelo¹, Marie Billecocq¹, Thomas Fussinger³, Mirjam Studler¹, Myles Capstick³, Niels Kuster³, Peter Acherma^1,4, Reto Huber^4,5, Hans-Peter Landolt^1,4 have worked together with the Institute of Pharmacology and Toxicology, Zurich¹, the Department of Psychiatry, Psychotherapy and Psychosomatics, Psychiatric Hospital of the University of Zurich², the Foundation of the Swiss Federal Institute of Technology Zurich³, dem Competence Center Sleep and Health at the University of Zurich⁴ and the University Children's Hospital Zurich⁵ examines whether

"... the allelic variant rs7304986 in the CACNA1C gene, encoding the α1C subunit of LTCC, modulates 5G RF-EMF effects on EEG spindle activity in NREM sleep."

"... the allelic variant rs7304986 in the CACNA1C gene, which encodes the α1C subunit of LTCC, modulates the effects of 5G-HF-EMF on EEG spindle activity in NREM sleep."

The conclusion of the study results is described as follows:

„These findings suggest that 3.6 GHz 5G RF-EMF modulates spindle center frequency in NREM sleep in a CACNA1C genotype-dependent manner, implicating LTCC in the physiological response to RF-EMF and underscoring the need for further research into 5G effects on brain health.„

"These results suggest that 3.6 GHz 5 G RF-EMF increases the spindle center frequency in NREM sleep in 
CACNA1C modulated in a genotype-dependent manner, implying that LTCC responds physiologically to RF-EMF and emphasizing the need for further research on 5 G effects on brain health."

Conclusion

As early as 1999, a study "Pulsed high-frequency electromagnetic field affects human sleep and sleep electroencephalogram" demonstrated that RF-EMF, at that time still comparatively low-frequency (900 MHz) radiation, at a SAR^* of maximum 1W/kg have an effect on sleep quality and EEG.

As development progressed, the original analog technology was replaced by digital technology. While a continuous transmission power is generated in analog operation, digital technology generates pulsed transmission signals with significantly higher power and therefore also higher radiation exposure.

As the G value increases (2G, 3G, 4G (LTE) or 5G), the transmission frequency also increases, and with it the amount of data that is transmitted per unit of time.
The need to transmit more and more data in less and less time inevitably results in ever higher frequencies and increasing power levels: the higher the frequency, the shorter the range for the same transmission power.
Why? While low frequencies penetrate walls, trees, rain and snow well, the attenuation increases with increasing frequency, which in turn has to be compensated for with higher transmission power and more densely positioned transmitting antennas.

This increases the power density and the risk of radiation exposure, the effects of which are countered today with limit values, but which, as in other areas, neither guarantee the absence of damage to health nor provide the certainty that they have taken into account all possibilities of biological influence when setting these values.

^*SAR (Specific Absorption Rate) represents the absorbed RF power per unit mass, in other words, the amount of heat stored in the body tissue.
