First animal study to date: 5G damages the brain

Published 7 March 2023

The first study to date to study the effects of 5G-like mobile radiation on animals observed severe brain damage after only one month of exposure for 2 hours per day. In the exposed animals, there was an increased incidence of damaged neurons in the part of the brain (hippocampus) that is important for memory and learning, among other things. In the long term, this increases the risk of dementia.

The research team that carried out the experiments is based at various universities in Turkey and the results were published in October 2022 in the scientific journal Journal of Chemical Neuroanatomy.

A total of 28 rats were included in the experiments. Half were exposed to 5G-like radiation (3.5 GHz, GSM modulated). Half were unexposed controls. Half of the exposed and unexposed had diabetes while the others were healthy. The reason was that the researchers wanted to investigate whether 5G had a particular effect on diabetes. The exposed animals were exposed for two hours a day, five days a week for a month.

Exposure far below the ICNRP limits

The exposure level of 1.6 W/m² was well below the current reference values for permissible radiation from 5G, 4G and 3G recommended by the Radiation Safety Authority of 10 W/m² and developed by the controversial organisation ICNIRP. The Radiation Safety Authority claims that 10 W/m² averaged over 6 minutes would protect everyone by a wide margin of demonstrated adverse health effects, despite the extensive evidence to the contrary and the complete lack of scientific evidence that such high exposures do not lead to adverse health effects when people are exposed for longer periods as in real life situations.

Can cause dementia

The results of this first 5G animal study show that 5G exposure led to damage to neurons in the part of the brain that is important for memory and learning (the hippocampus), among other things. Neurons are a type of cell that receives and sends messages from the body to the brain and back to the body. The messages are sent by a weak electrical current.

The damage increased in both exposed groups compared to unexposed controls and was worse in the diabetic group.

In both exposed groups (healthy and diabetic), increased oxidative stress was seen in the brain and the effect was greater in the exposed diabetic group.

This shows that prolonged exposure to 3.5 GHz can lead to dementia in later life, the researchers write.

Affected hormones that regulate appetite

The researchers also observed that the radiation affected levels of nesfatin, irisin and ghrelin.

Ghrelin is a hormone that stimulates appetite. Previous research has shown a link between increased food intake and exposure to similar radiation, and scientists have suggested that radiation from wireless technology may have contributed to the epidemic of obesity seen in much of the world. Weight increased more in the healthy 5G-exposed group compared to the unexposed group, but not in the diabetic group.

Nesfatin is also involved in the regulation of food intake, but the hormone is also important for other brain functions such as stress, mood, sleep and also has a protective effect on the nervous system.

Irisin has been recognized for its importance in the treatment of metabolic diseases such as obesity and diabetes, but also for the treatment of degenerative diseases.  Irisin which is produced during exercise, has anti-inflammatory effects, counteracts oxidative stress and is generally considered to have a protective effect on the central nervous system.

Swedish research showed neuronal cell death in 2003

The Swedish research team at Lund University Hospital, including brain surgeon Professor Leif Salford, published results back in 2003 showing that GSM radiation caused neuronal death in the brains of experimental animals. The results were published in the scientific journal Environmental Health Perspectives in the article Nerve cell damage in mammalian brain after exposure to microwaves from GSM mobile phones

In an interview with BBC in the article “Mobile phones ‘may trigger Alzheimer’s'”, Professor Leif Salford said in 2003 that the results show that radiation could cause Alzheimer’s disease, which occurs earlier in life. As in the new 5G study, the animals were exposed to radiation well below permitted levels for just 2 hours a day for 50 days.

800 studies

According to Professor Henry Lai’s summary 2022, almost 800 studies showed that radiation from wireless technology causes oxidative stress, genetic effects/DNA damage or harmful effects on the brain. Already in 2004, a major EU-funded research project called REFLEXconvincingly showed that mobile radiation causes DNA damage in cells.

Has been rejected by the authorities for years

These serious findings have been rejected and belittled by the responsible authorities in Sweden since 2003, and have continued to be so for years, partly by reference to their expert evaluations, which have always been dominated by individuals with conflicts of interest in the form of membership of ICNIRP and/or funding from the telecom companies. ICNIRP has, as mentioned above, established existing radiation limits of very high economic importance for the telecom companies, which would prove insufficient if adverse effects below these limits were to be recognized.

ICNIRP has been criticised for many years. Most recently in an article from the new International Commission on Biological Effects from EMF, ICBE-EMF, which concludes that ICNIRP’s limits are based on outdated and erroneous assumptions that radiation can only cause harm if it is so intense that it leads to immediate thermal effects – although this has been disproved in recent years by hundreds of research results. ICBE-EMF therefore calls for new, significantly lower limits to be developed and for the further roll-out of 5G to be halted.

Radiation Protection Foundation: 5G is a crime against the people

5G has been rolled out on a large scale over the past two years without any research showing that the technology does not harm human and animal health. As of February 2022, no research had been done on the impact of 5G on humans, animals or the environment in general. The French authority ANSES in January 2020 concluded that there was no research at all on the effects of the frequencies 5G uses (frequencies between 3 and 4 GHz and 26 GHz). The first study to date to look at the effects of 5G is a Swedish case study reported by the Radiation Protection Foundation in February 2022, which showed that a 5G base station caused a dramatic increase in radiation exposure in a home and such severe symptoms in a short period of time that continued living in the home became impossible.

Many scientists and organisations working on the issue of the health risks of this form of radiation have issued critique and warned. Over 400 scientists and doctors have signed the 5G Appeal since 2017, stating that there is a complete lack of research studying the effects of 5G and that a moratorium on 5G should be imposed as there are concerns that 5G could cause serious potential health consequences.  5G will lead to a massive increase in radiation that has already been proven to be harmful at frequencies used for previous generations of telecommunications.

In the light of the first two studies ever done on 5G, the scientists’ call for a moratorium should be heeded and deployment halted. Continuing to forcefully expose people to proven harmful radiation – which at the same time has never been shown to be harmless – must be considered a gross violation of international law. The exposure is not voluntary and has not been made with informed consent. A base station can be set up in the vicinity of people’s homes from one day to the next without the residents concerned being informed in advance. Only an agreement with the property owner of the site where the base station is to be erected is required.

Mass exposure of people to radiation that has been repeatedly shown to cause such damage, which can ultimately lead to degenerative diseases and cancer, is undoubtedly a serious crime and the fact that this can continue shows that something is seriously wrong.
