SAR norms not suitable anymore
The ‘SAR’ standard used in Smartphones -like the iPhone- for measuring exposure of human tissue to radio signals has been heavily disputed over the last few years. The main reason for this is, that the SAR standard ONLY looks at energy absorbtion and subsequent tissue heating effect. Recent studies have shown, however, that the REAL risk is not in heating cell tissue, but in the devastating effects pulsating radiosignals can have on living Human cells and the mitrochondrial DNA of (neurological) cells. Especially in Asia, a lot has been published on the effects of GSM signals to human tissues and human health.
Transmission Frequency and Transmission Power
In GSM’s and Smartphones the radio transmission frequency ranges from ±800 Megaherz (0.8 Gigaherz) to ±5000 Megaherz (5 Gigaherz). The power emission of these devices is adjusted automatically; based on the distance a device has to the ‘tower’. In practice the High Frequency power emission of a hand-held device like a Smartphone ranges from about 5 dBm to about 35 dBm That would be between 0.0031 Watt and 3.162 Watts. The scientific research in below papers has used exactly the frequency ranges as well as the HF power most commonly emitted by modern phones. So circumstances were tested that are similar to normal cellphone use.
An important aspect in digital radio communications is the extreme ‘pulsyness’ of the radiosignal. Transmitting digital information has the consequence that you not only broadcast pretty ‘dense’ signals; Because of the ‘slicing’ effect of digital modulation, a lot of undesired frequencies are generated in the process. All in all this leads to a pretty powerful ‘signal-soup’ of which the effects on human (nerve) tissue are not yet very well known. Strangely enough the build-up of GSM infrastructure nowadays has taken a higher pace than the research on the effects in humans has.. We have gathered some scientific studies in this field, and the outcomes -for now- are pretty alarming. So for now we can only say: stay alert and keep yourself informed!!
’10 Recommendations for EMF Safety’

The technologies and standards that are covered in this publication are Smartphones and GSM’s; WiFi; Bluetooth; DECT telephones; Plasma TV’s, TL-lighting; CFL lightbulbs (‘low energy bulbs’)PC’s; Power lines.
Electro Magnetic Field (EMF) Safety Standards. Generic safety standards for equipment using high frequency electromagnetic fields, including DECT telephony, Radio, TV, WiFi, GSM, Smartphones, Bluetooth and more.
‘The influence of human head model wearing metal frame spectacles to the changes of SAR and antenna gain: simulation of frontal face exposure’. by Mohd H. Mat, Fareq Malek, William G. Whittow,Suzanna H. Ronald, Muhammad S. Zulkefli, Norshafinash Saudin, and Latifah Mohamed. Article on the unexpected HF energy spreading effects of metal spectacles (yes, glasses!) in strong GSM / Smartphone fields. The article adresses effects in the 0.9 Gigaherz as well as the 1.8 Gigaherz range. Modern Smartphones and GSM’s use both the 0.9 Gigaherz as well as the 1.8 Gigaherz band in a pulsating fashion.
‘Oxidative changes and apoptosis induced by 1800-MHz electromagneticradiation in NIH/3T3 cells’ by Qingxia Hou, Minglian Wang, Shuicai Wu, Xuemei Ma, Guangzhou An, Huan Liu, and Fei Xie. Article on cell damage and cell death as a result of pulsed electromagnetic radiation in the 1.8 Gigaherz range. Modern Cellphones use the 1.8 Gigaherz band in a pulsating fashion.
‘Exposure to 1800 MHz radiofrequency radiation induces oxidative damage to mitochondrial DNA in primary cultured neurons’ By Shangcheng Xu, Zhou Zhou, Lei Zhang, Zhengping Yu, Wei Zhang, Yuan Wang,Xubu Wang, Maoquan Li, Yang Chen, Chunhai Chen, Mindi He, Guangbin Zhang, Min Zhong. Article on the influence of pulsating electromagnetic radiation in the 1.8 Gigaherz range on human mitrochondrial DNA and on human neurons. Modern Smartphones and GSM’s use the 1.8 Gigaherz band in a pulsating fashion.
Toezichtarrangement Mobiele Communicatie by Agentschap Telecom (Central Dutch Governmental Agency governing Telecommunication Services). Legal description of the way the ‘Agentschap Telecom’ will monitor and enforce the permits for public electronic communication networks in the 800, 900, 1800, 1900, 2100 en 2600 MHz band. (0.8 Ghz; 0.9Ghz; 1.8 Ghz; 1.9Ghz; 2.1Ghz; 2.6 Ghz bands. The article describes test methods and -circumstances; field strength norms and measurement methods as well as base station transmission power to the parties involved in the Netherlands. (Ziggo, Vodafone, T-Mobile, KPN and Tele2). My observation: The average transmission power of 2.6 Ghz base stations is allowed to be around 52 dBm and the peak power around 62dBm. This equals 158,48 Watts, resp. 1258.925 Watts. Scary!! That is more than a microwave oven (typical 900 watts @ 2.450 Ghz) Furthermore all parties involved ar forced to obtain a minimal field strength in the area’s they service. This will undoubtedly influence the amount of transmitters as well as the transmission power used tremendously…
5G ‘buzz word’
There has been a lot of ‘fuzz’ in the media surronding ‘5G’. Other than you might think, 5G is not only about ‘higher frequencies’ or ‘more transmitters’. Whilst 5G might use higher frequencies and more transmitters, it is at the same time ALSO a totally new protocol to create wireless connections for digital signals.
This intelligent ‘5G-protocol’ is highly virtualized and works ‘under water’ with the ‘TCP-IP’ protocol (the most important internet protocol). It is designed to be able to use the old 3G/4G GSM infrastructure as wel as the new infrastructure designed for 5G. What is significantly different for end users is, that you can have more than one connection with the infrastructure at a given point in time. For more in-depth on this subject, please read our page on 5G consultancy.
What can you do TODAY to protect yourself?
The amount and the intensity of pulsating high frequency signals will increase in our living environment. What you might not know, is that you can actively shield yourself partially from these harmful radio signals. For in-depth advice on how to approach this, detailed measurements have to be taken on the spots you work, live and sleep. But you can compensate for all of this yourself, by adapting your behavior.
Here is a set of measures you can take immediately to reduce the negative effects of high frequency fields on your body considerably:
- Strange as it may sound: Never hold your phone against your ear during phone calls –> always use a headset or -better- put your call ‘on the speaker’.
- Never wear your phone directly on your body. (like in your breast pocket, your bra, your back pocket) but at minimally 5 mm distance from your skin. Apple recommends this in the ‘legal notice’ that is stored in every iPhone.
- Never ever make a call in the car. If you really have to, than position your phone antenna (1) next to the back mirror, or (2) in the left bottom corner or the (3) right bottom corner of the windshield. (this is where the 3 ‘holes’ are situated in your ‘Faraday cage’; originally meant for navigation devices in order to facilitate the reception of GPS satellites.)
- This advice also holds for any other device with a SIM card (like a GPS tracker, TomTom, iPad e.d.)
- During the night, Put your Smartphone, Ipad and other devices with a SIM card on ‘flight mode’.
- Never ever sleep next to your phone when it is not on flight mode.
- Put the WiFi in your house at the lowest output power possible (see: ‘settings’)
- Put your WiFi totally off during the night (you often can automate this..)
- Switch off all other WiFi sources (like Printers, Camera’s, etc.; you often can automate this..)
DECT based telephones and babyphones
- Immediately remove all DECT based telephones from your house. So: Do NOT use. Ever!
- Do NOT use ‘babyphones’ based on DECT .
- Ask your providers to remove all the smart meters they installed in your house.
