Are Base Transceiver Station and Mobile Healthy?



This is very common issue for many people and actualy. So we decided to explain this topic in scientific way.
RF is non -ionizing radiation category like Microwaves, Infrared etc. On the other hand,  ultraviolet, X-Rays, Gamma Rays are in ionizing radiotion category.

GSM Standards are defined by ETSI (European Telecommunication Standardization Institute) in Europe and FCC (Federal Communication Commission) in USA. Since RF is non-ionising radiation;
ICNIRP (International Commission on Non-Ionizing Radiation Protection ) rules are means a lot to us. WHO (World Health Organization) and ILO (International Labor Organization) recognizes the ICNIRP studies. Europe Countries take ICNIRP radiation limits about human health. In USA, FCC takes care the IEEE (Institute ofElectrical and Electronics Engineers) And ANSI (American National Standarts Institute) studies.



So , for GSM users like us, following values are important for us;



What is the meaning of above values?
Above things are just hazard limits  of RF and it is based on 0.1 celcius increasing human body heath.
On the other hand, In Turkey, above limits are more safety than Europe Countries.

As a result,

Output power of mobile phones dynamically changes according to distance between antenna tower etc. Average power is  1W, maximum 2W (it is up to GSM frequency too) and  Output power of BTS antenna is maximum 60W.  These values are not enought to heat water actually. This is good for us.
Also There is no clear evidence between cancer and GSM equipments. But it does not indicate that everything is green. Authorities are still searching the relationship between  Radio Frequncy and Human Health.
And please do not forget, somethings which seems innocent for people generally but it is more dangerous than GSM Freq. like High Voltage Lines.

We can just do following for better protection:
  1. Do not make a call in your call without using any special kit. As, only one proof about hazard of GSM is, talking with mobile phone while driving, increases traffic accident risk :)
  2. Do not make long calls or use headset etc
  3. Try to keep distance your body and mobile
  4. Distance between antenna and human might be at least ~9 meters.
