The Bio-inititive report is a report on the potential effects Electromagnetic Fields and Radio Frequencies can have in our health. It addresses GSM microwaves as well as WiFi ones and, as far as I can tell, it is quite exhaustive; 610 pages.
“Human beings are bioelectrical systems. Our hearts and brains are regulated by internal bioelectrical signals. Environmental exposures to artificial EMFs can interact with fundamental biological processes in the human body. In some cases, this can cause discomfort and disease. Since World War II, the background level of EMF from electrical sources has risen exponentially, most recently by the soaring popularity of wireless technologies such as cell phones (two billion and counting in 2006), cordless phones, WI-FI and WI-MAX networks.”(bioinitiative report, 2007)
The truth is, that our households are increasingly being penetrated (aka exposed) by a larger number of devices transmitting microwaves at different frequencies. You can run a quick scan of wifi networks each year and state the difference by yourself. Now, as an exposure to something (as was being exposed to charbon-based heat or smoke filled discotheques), I guess medical evidence will highlight what the dangers (or benefits) are.
Regardless of how dangerous EMF are or might be, it is interesting to note how accurate the management of collective health and collective awareness of “threatening invisible signals” (such as microbes; not only microwaves) has become. One of the CSI students here at l’Ècole des Mines, Julien Gauthey, made my day by helping me discover two words;
“electrosensibles”; aimed at people who are more affected than others by EMF or RF. and:
“expologie” (with and “y” at the end instead of the “ie” for an english conversion): sort of science of those being exposed to threatening signals. Sort of epidemiologie carried by other means. Signals and alerts, for instance.
Now, it would really be a great paradox to start seeing “wifi free” areas instead of “free wifi” ones now that so many effort is being made to populate the EMF
Time will tell (everyone is willing to be connected to digital networks, no one is willing to get a cancer. No perfect drug (NIN dixit) for the time being)
Before ending this post, it is worth noticing that although the term wifi appears on the bio-initiative report webpage and in quoted text here also, it should not be equaled to GSM and other EMF radiations that are far more powerful than wifi. In deed, if one reads the report conclusions;
The lower limit for reported human health effects has dropped 100- fold below the safety standard (for mobile phones and PDAs); 1000- to 10,000-fold for other wireless (cell towers at distance; WI-FI and WLAN devices). The entire basis for safety standards is called into question, and it is not unreasonable to question the safety of RF at any level. -they further elaborate and propose a minimum threshold-; A cautionary target level for pulsed RF exposures for ambient wireless that could be applied to
RF sources from cell tower antennas, WI-FI, WI-MAX and other similar sources is proposed. The recommended cautionary target level is 0.1 microwatts per centimeter squared (μW/cm2)** (or 0.614 Volts per meter or V/m)** for pulsed RF where these exposures affect the general public.”
But a cell tower IS NOT a WiFi tower. I think we shoud be able to distinguish the intensity and power of those radiations so as to have a comparison scale. Because otherwise we might leave room for unnecessary alarmism concerning wifi (wich is NOT gsm).
