USEFUL HINTS TO AVOID POSSIBLE ELECTROMAGNETIC RADIATION HEALTH HAZARDS

GENERAL ADVICE: Any device producing electromagnetic field is potentially harmfull. Avoid close contact with vital parts of your body and especially if you are pregnant or a child. The overall effects depend on a) the distance from the device, b) the strength of the field and c) the duration. Try to compensate with all these factors

MOBILE PHONES

*       Never use the phone close to your head, use hands free or blue tooth (wired preferably) but having the clip away from the body

*       Do not keep the phone in your pocket without a shielded case since it emits radiation occasionally evn if not in use.

*       Do not keep the phone (unless in flight mode) next to your bed during sleeping

*       Use the phone very shortly when in low signal regions, i.e. in closed environments or far away from mast antennas of the same provider (check the bar signal indicator to find out)

*       Pregnant women and children of any age should not use the phone unless for emergency purposes.

*       Sending sms is safer than talking with the phone next to the head provided that the phone is away from the body during emission of the message(s)

       In case of using a smartphone or i-phone, install and run a blue light filter application to reduce the blue light emitted by led screens which interferes with tour sleep.

WIRELESS D.E.C.T.  DEVICES

    General information : The DECT devices (digital enhanced-european-digital telephones) consist of two parts: A base and the handset. The base upon pluging into the mains emits continuously radiation scanning through the allocated 10 channels in the frequency band of 1890-1900 MHz. The handset emits radiation only during a call. Both kinds of emissions are harmful as have been shown by published and unpublished research. Last years' models (some of them, very expensive) have the feature to turn off the radiation of the base when the handset in put on it. The same models claim that lower radiation is emitted (ECO=economy models). Research has shown that this radiation is equally harmfull with the monile phones' and is responsible for brain tumors, fatigue, sleep disorders, e.t.c. IF USED WITHOUT PRECAUTIONS AS STATED ABOVE

*       Have the base unit as far away as possible from places that people use to sit or sleep. If possible replace the DECT with a land line.

*       Do not allow children of any age and pregnant women to use the DECT.

*       If  necessary to use the DECT, either use a hands free earphone during a call (available in some models) or use open conversation mode and in any case make the call short switching to the land line.

*       Unplug the DECT base during the night because even the slightest radiation may disturb your sleep, UNLESS YOU OWN AN ECO MODEL, suitably adjusted through the MENU utility. You do not enter the "deep sleep" phase and the next day you most probably will be nervous.

WIRELESS NETWORK (WI-FI ROUTERS)

General information: These devices normally emit continuously radiation scanning through  channels in the frequency band of 2440 MHz. our research group has shown in flies that this radiation is equally harmful to a mobile phone kept on contact with the body because it emits high intensity pulses although the average intensity is very low. The intensity becomes higher during coupling with a wi fi device, a laptop, a cell phone or a tablet downloading files. DOWNLOADING MEANS THAT THE ROUTER EMITS MORE RADIATION IN ORDER TO SEND THE DATA TO THE DEVICE.

*       Keep the device as far away from children and pregnant women (at least 5 meters)

*       Turn off the device at night, or use a special covering reducing its radiation to a minimum

*       If not absolutely necessary replace the wireless connection with wired ftp cable

*       Never keep a laptop operating in wireless mode on your knees, or turn off the Wi-Fi mode

*       Do not allow children to play games through the internet with wireless connection because during the play their device is sending data to the router thus emitting radiation. It is better to play games stored in the device and not on line, unless wired connection is in use.

FINAL HINT: ELECTROMAGNETIC FIELDS ARE INVISIBLE AND CANNOT BE DETECTED BY ANY ORGANISM BUT THEY ARE POTENTIALLY HARMFUL AT ANY POWER LEVEL. THERE IS STILL NO VALID SCIENTIFIC EVIDENCE FOR THE EXISTENCE OF A SAFETY LIMIT
