We are living with new technologies but now is very dificult compare the efefcts on human health

The effects include cancer promotion, reproductive problems and symptoms of electro-hyper-sensitivity due, in part, to physiological stress induction. There is a lot of information in the literature. The BioInitiative Report presents some of the evidence but there are many other sources. Feel free to visit my website: www.magdahavas.com and watch my youtube videos www.youtube.com/magdahavas.

There is considerable controversy but scientists who are not funded by industry and those who have been studying this for years (rather than physics who rely on theoretical arguments rather than experimental observations) tend to agree that multiple effects from changes in membrane permeability, to NO production, to calcium flux, to production of stress proteins, to altered enzyme activity are documented and contribute to the mechanisms involved.

Controversy is a product of ignorance, incomplete understanding of the issue, and vested interest groups producing disinformation. This has happened time after time with things like DDT, smoking, asbestos, acid rain, PCBs, etc. It takes years wading through the muck to find the gems that shed light on this issue.

My personal experience is that it effect on your temperament or nervous system and people who remain in the exposure of radio frequency or microwave for long long time get irritated so often.

Their question is very interesting, in this sense, one of the epidemic studies of more span that have been carried out on the matter, Interphone, where they participated 13 countries, he/she didn't reveal an increase of the risk of two types of tumors - glioma and meningioma - with the use of the wireless telephone along a superior period to the 10 years. However, they were certain indications of an increase of the glioma risk in people with more accumulated hours of use of the cellular one. Cardis, main investigator of the study, indicates that neither you/he/she is descartable that “there were biases” in the investigation since people that suffers a cancer usually wonder which the cause has been and it can attribute its illness easily to the motive.

On the other hand, the patients that participated in the study began to make use from the mobile telephony to a later age that today's youths in day, since a cancer or tumor can take years in showing. For this reason the OMS considers that the investigations should be deepened in population's groups. In these moments, they are carrying out diverse studies that you/they investigate the possible effects on the health of children and adolescents.

The result of investigations like this it has taken to the International Agency for the Investigation on the Cancer (IARC), integrated in the World Organization of the Health (OMS), to classify the radiofrecuencia EMF (RF) associated to the use of wireless telephones like possible carcinogen for the humans (Group 2B). The incognito ones that exist around the effects on the human body that can have a lingering exhibition to wireless devices motivate the experts to recommend to take some measures of caution that are detailed next:

- To move away the telephone of the head, to speak with the free hands or to send text messages contributes to minimize the exhibition to the radiations.

- To place the point of access wi-fi at least to a meter of places where people usually remain for more time, as beds, tables, sofas or areas of games.

- The transfer of big files of data or streaming multimedia should only be carried out when the established connection between the portable device and the access point in a room is of good quality to avoid retransfers that lead to the highest work cycles and the highest exhibitions.

- It is advisable that the consumers adopt the use of terminal teams that you/they implement protocols of telecommunications with control of power. When these they are available, for example, ECHO DECT instead of DECT.

- In the places where a connection Wi-Fi is frequently used the covering it should be the sufficiently good thing.

- The access points should be out when they are not in use, because, even when the connection wi-fi, the apparatus is not used he/she sends buoy signs on each 102 meters.

- In public spaces it is preferable to install a single net Wi-fi that of covering to all the teams or to return to the old internet system for cable.

The study Seawind, financed by the UE, concludes that the main factor of concern for the exhibition to radiations is the use of motives in voice way with the device near the head. And he/she adds that the use of a support or free hands cause high similar exhibitions of the regions of the body that are near the telephone. As for the wi-fi, it concludes that the exhibition levels are in general very low, except when you is very near an access point or a mobile device through wifi. In this last case, the value SAR maximum - power with which an electromagnetic field of radiofrecuencia is absorbed by the alive fabric - it can be as high as that of the wireless telephones.

Here is a story about the release of some early results of a large study that shows that there is some impact on cancer rates from the use of cell phones.
