Die Studie untersucht den Einfluss der Exposition gegenüber Hochfrequenzsignalen von Mobiltelefonen auf den Glukosestoffwechsel im Gehirn. In einer randomisierten Crossover-Studie wurde der Glukosestoffwechsel im Gehirn von 47 gesunden Teilnehmern gemessen, während sie für 50 Minuten einer aktivierten und einer deaktivierten Mobiltelefonexposition ausgesetzt waren. Die Ergebnisse zeigen, dass eine 50-minütige Handy-Exposition mit einem erhöhten Glukosestoffwechsel im Gehirn in der Nähe der Antenne verbunden war. Dies widerlegt die langjährige Behauptung, dass es keine biologischen Auswirkungen nichtthermischer Strahlung von Mobiltelefonen gibt. Die Studie betont die Notwendigkeit einer gründlichen, unvoreingenommenen Betrachtung der Risiken bei der zunehmenden Nutzung von Mobiltelefonen. Details der Studie: Referenz Volkow …

Design

randomized crossover study

Setting

study carried out between January 1 and December 31, 2009 in a single US laboratory.

participant

47 Healthy participants from the community recruited

study method

mobile phones were attached to the left and right ear and the glucose metabolism in the brain was measured using positron emission tomography, with the exposure compared to an activated and a deactivated mobile phone for 50 minutes.

result measure

The glucose metabolism in the brain is calculated as an absolute metabolism (μmol/100 g per minute) and as a normalized metabolism (region/entire brain).

most important knowledge

In healthy participants, a 50-minute mobile phone exposure was not associated with an increased glucose metabolism in the brain in the region, which is closest to the antenna.

effects on practice

For years, medical experts and scientists have expressed concerns about the questionable security of mobile phone use, but despite the increasing evidence, it is difficult to resist this tempting technology. The increasing use of mobile phones by humanity, 5 billion users worldwide, requires thorough, impartial consideration of the risks.

The study refutes the long -term claim to both the Federal Communications Commission and the mobile phone industry that there is no biological effects of non -thermal radiation of mobile phones.

the jama The study documents that exposure to mobile phones affects the brain by increasing brain glucose, a well -known level of increased brain activity. Although the study does not offer an explanation for the underlying mechanism, we know that in other biological systems of the body, a chronic increase in glucose can have significant effects on the local tissue and can change cell and gene function. In particular, the study refutes the long -standing claim of both the Federal Communications Commission and the mobile phone industry that there is no biological effects of non -thermal radiation of mobile phones.

The published studies on cell phone use and the possible health risks (including tumors of the brain, 1 as well as male infertility 2 ) are numerous and many. One of the study catalogs, which are often partially financed by the mobile phone industry, also includes a meta-analysis that was published in the published magazine for clinical oncology in 2006 and almost 38,000 participants came to the conclusion that increased health risks exist. Branch of the World Health Organization called "International Agency for Research on Cancer" (IARC) 31 scientists from 14 countries, including the United States, called together, evaluated studies on the security of mobile phones and issued an explanation in which the exposure is determined compared Auto exhaust: Possibly carcinogenic.

When do we recognize that precautionary measures have to be taken? Our current security standards for mobile phones are based on outdated research results. They certainly do not take into account the dramatic increase in user numbers, the increase in useful life and the increasing use of mobile phones by young people. Not only the effects on the brain tissue must be further examined, but also the consequences of strong use and long -term exposure - parameters that have not yet been examined.

The concept of the precautionary principle encourages political decision -makers to make decisions that the public protect against possibly harmful policy or measure, provided there are no final data. When considering the health effects of electromagnetic high frequencies of mobile phones, the public must be protected against the damage that can arise from their use. It is reminiscent of our history in relation to tobacco when medical professionals were waiting for final studies data for decades, while millions of people suffered foreseeable health consequences. By refusing now to recognize the possible health risks of mobile phone use, we may harm future generations.

While we continue to collect information, we can advise our patients about the many options for reducing the entire electromagnetic radiation exposure:

  • switch off mobile phones if they do not use them. Mobile phone emissions always occur when the phone is switched on, regardless of whether it is used or not.
  • Avoid using mobile phones if the signal is weak. The emissions rise while the phone is looking for a broadcast.
  • keep mobile phones away from the body in a handbag, a backpack or a briefcase.
  • Use a protective headset that creates the distance between the phone and the brain, if possible with corded earphones.
  • Write SMS instead of phone calls.

We can assume that the technology will be further developed, including safer phones and safer designs for towers. Ultimately, the restriction of mobile phone use - i.e. the use of our mobile phones for really important communication and the elimination, could be the key to risk reduction.
