8 things about Mobile Networks Antenna Radiation and its effects on HEALTH
Mar
Antenna Radiation! How unlovely it sounds. It makes people feel desperate. Once it comes, there is noway to run. It travels with the speed of light after all.
That perception might be originated from some historical events like atomic bombs or Chernobyl Disaster. Before riding into the topic, we should first differentiate good and bad radiation very shortly.
Sun light itself is a type of radiation, our source of life in this planet. X-rays used in the way discovered by Wilhelm Conrad Rontgen are also radiation. Have you ever mentioned the caution about pregnants on those machines?
In addition, gamma rays that come out from a nuclear reaction and any sort of wireless signal produced by any sort of wireless device we heavily use give off radiation. How to decide which one is good or which is bad and how to protect ourselves from the latter.
That knowledge have a big impact on our health and life quality since it is impossible to avoid ourselves completely. I will concentrate on the last group which I believe know-how level is quite low among people despite the fact that the level of engagement to mobile technologies is quite high.
Do you ever know that there exists some academic researches proving how smoking makes people healthier? That was of course many years ago. But even only this should be enough on forcing us to be so careful with wireless devices.
X-rays are the beginning of unquestionably bad radiation on the spectrum. Its frequency is on 1015 Hz level. Wireless mobile networks use frequencies around 109 (Gigahertz). Million times weaker, how soothing it is.
But radiation power also means much, that is the reason why wireless devices may harm living tissues. Let’s leave the physics and biology lying behind to a further time and begin some daily life advices.

Now 8 things that you do not know about mobile networks radiation phenomenon.
- The most harmful component of mobile networks is what we carry on our pockets, the cell phones, not the base stations.
We have a parameter called SAR (specific absorption rate) which is an indication of the amount of radiation that is absorbed into a head whilst using a cellular phone, the higher the SAR rating the more radiation that is absorbed into the head. (sarvalues.com).
The question is, comparing a 50W (average power level of high coverage base stations-the most powerful ones) base station that is hundreds of meters away and a 2W cell phone just next to your head? It is like putting your head in a low power microwave owen!
What is meaningful is electric field density, which diminishes by square the distance from the antenna radiation. Thank God we cannot surf the internet while the cell phone is on our ears. That’s because 3G&4G connections need higher power levels. You can easily imagine how high it is from battery consumption rates! Hours of talking may equal to a quarter of surfing.
We have a simple and very effective solution. Always use earphones. Wired ones! That is the most crucial precaution that one can take.
- In case of emergancy or when your Mom’s calling or your girlfriend, they may be so angry or anxious and there is definitely no time to put on earphones, what should we do then?
Hold the phone having 15 degrees to your cheek while talking. That is the angular position that device radiation level is minimum on your brain.
- In addition, cell phones radiate at max just after touching “Send” button for SMS messages and “Call” button when you initiate a voice call. Put to phone to your ears 2-3 seconds after the beginning of the conversation if you cannot use earphones.
- Cell phones that have two SIM card slots includes two distinct cell phone transmission units in it. So keep away unless you have to.
- Cell phones send some sort of attendance signal at any time on a regular basis (like once in 10 min) while it is up and running to the nearest base station, like “Hey boss, I am here, how are you?”, and responded as “Thanks buddy, nice to hear you!”.
This is a short signal but putting the cell phone away from your hill while sleeping would be wise. I am hearing those grumbling about alarm clocks. An analog clock is more than enough, old style.
- Base station antennas are “dipole” antennas (a more showy way of saying “stick”). It is the nature of dipoles that they radiate mainly towards to perpendicular direction and almost do not radiate upwards (that is what birds should be pleased of) and downwards (that is about Homo Sapiens!).
Comparing a base station at the top of your roof and the roof of the very next building, the first one definitely wins (even when you do not take the rental income into account).
- Each and every ICT Authority (FCC in US) use an exposure limit for base stations. It works like limiting the E-filed density to some level at the nearest public area (house of a neighbour or a restaurant or any other place) from a base station.
ICNIRP (the International Commission on Non-Ionizing Radiation Protection) makes the necessary academic work and defines values but many countries restrict mobile operators to much lower levels. States in the US may use different limits as well. So that might be a good idea to web-search about your state of residence.
- It makes much more sense, in radiation exposure point of view, to have numerous amount of base stations which have very low power emissions than less with very high powers.
For households, a femptocell solution (mobile network via fixed network infrastructure) can be a possible option if the nearest base station is a little far away, to avoid from radiation of cell phones.
Namely, it is good to deploy a very small indoor base station at home (not to any bedroom of course!)
In conclusion, it is not that hard to avoid harmful radiation while benefiting the blessings of new technology. Just don’t roll with the punch, since the subject is your most valuable asset, your health.
