Het leed dat vooruitgang heet

"The real problem:
The real problem however is that the DECT design is plain stupid: The base station sends this same powerful signal 24 hours a day, even when you wouldn't use the phone a single time that day. That means that also during sleep, the DECT base station keeps sending this strong signal.
The DECT base station can be compared with a cellular phone transmitter antenna in your backyard, at only 20 yards distance !
Field-strength meassurement device
Using a field-strength meassurement device you can assess the strength of the transmissions of the DECT phone. On the HF-Detektor II Profi from www.aaronia.de all red lights are turned on when the DECT base station is plugged in. When it's removed the LED's show the normal background level (which depends on the proximity to cellular phone transmission antenna's nearby)..
Some details
The DECT base station turned out to be really bad. At 5 centimeter (2 inch) range, it's -0 dBm (all red lights on), at 50cm it's -8 dBm and at three meters still -17 dBm. And that all day long, all night long !"

"Een DECT basisstation dat in het stopcontact is gestoken is (qua resulterende veldsterkte) vergelijkbaar met een GSM zendmast op 20 meter afstand."
http://www.tetrawatch.net/science/dect.php
"All modern (DECT) digital cordless phones emit the same type of pulsed microwave radiation (about 1.8 GHz) as ordinary (GSM) mobile phones. Emissions can be about 6 V/m within a metre of the base unit, for as long as it is plugged in. These base stations emit their radiation even when the phone is not in use. All DECT base units emit microwaves continuously 24 hours a day as long as they are plugged in. For this reason cordless phones are regarded as bad news."
"Unlike mobile phones, DECT cordless phones work at a fixed power. Mobiles turn their power down to the lowest level possible, so when you are near a base station this can be much lower than a DECT cordless. DECT pulses are far more aggressive than for mobiles"
Dat is ronduit verontrustend.
Temeer daar dat ding toen (2003) aan de richtlijnen voldeed.

Wat splitsen ze (de fabrikanten) ons allemaal in de maag?
