Worried about mobile phone dangers, cordless phone dangers or cell phone dangers? Looking for EMF protection or EMF shielding?

The MW1 Electrosmog Microwave EMF detector measures the strength of microwave electromagnetic fields. Its principal domestic use is to identify the field strengths of the microwave-frequency electromagnetic fields emiited by mobile phones, cordless telephones and Wi-Fi-related devices, including mobile phone masts and base stations, in order to identify the completely safe and dubious areas in your garden, house, workplace and children's schools.

When switched on at full volume, the MW1 Electrosmog Microwave Detector emits a gentle hiss, actually the background radiation of the cosmos. When near a human-made microwave-emitting device, like a mobile phone, a phone mast or microwave oven, it expresses the pulsing microwave radiation you are being exposed to as an unpleasant clicking sound, a bit like a geiger counter. The sound is so alarming you will probably want to turn your MW1 down!

The MW1 begins to react at the levels that have been associated with adverse health effects, and will react to all microwave sources, including cordless phones, 2nd Generation (2G), 3rd Generation (3G - the current system), TETRA (the new police) masts, and microwave ovens.

A steadily growing number of concerned scientists believe that this human-made additional radiation is likely to be biologically hazardous, affecting all our bodily systems, making us more vulnerable to cancers, endocrine and neurological changes, thought and mood disorders, and other illnesses brought on by radiation of similar type and frequency.

The Warning Signals
The cosmic microwave sound is a gentle hiss. The human species has evolved with this constant companion. If you can hear anything more than a gentle background hiss with this microwave detector, you will be hearing human-made microwave pollution (electrosmog), that has only been in existence for about 20 years, and to which our bodies have not had time to adapt.

People vary in their susceptibility to microwave electromagnetic fields. Some sensitive people, those whose bodies tend to have allergic reactions to the environment or electrical fields, will react to very low levels of audible microwave EMFs. The louder the sound, the more such people are likely to be affected. The symptoms you experience will depend on what parts of your body are the most sensitive.

You will be able to hear the electrosmog surrounding you at field strengths of 0.05 V/m and possibly even lower. This is the level above which adverse biological effects are being repeatedly demonstrated in significant numbers of people. Some people react to levels even lower than this. A simple DIY modification can enhance the sensitivity of your electrosmog detector to 0.03 V/m or even lower.

The MW1 Electrosmog Microwave Detector allows you to hear the "aggressive pulsing" of microwave signals from mobile phone base stations (including TETRA and 3G), DECT cordless phones, mobile phones, microwave baby monitors, microwave burglar alarms, Bluetooth devices, wireless computer & laptop systems, etc. (all of which operate at frequencies between 50 MegaHertz and 6000 MegaHertz).

GSM base stations emit a harsh-sounding 1733 Hz (three octaves above concert A) high pitched whistle (full of high frequency signals due to the short 30 microsecond gaps between the pulses) from the base control carrier (BCCH), and a mixture of 217 Hz plus harmonics from the traffic channel(s) with very low frequency bursts and interruptions. The MW1 Electrosmog EMF Detection Unit allows you to hear the totality of the signals that your body is being bombarded with, so that you can find any "no microwave-pulsing" areas in your house and garden and test screening materials, etc.

UMTS (3G) base stations emit a 1,500 Hz high-pitched whistle and a mixture of complex modulation (heard as sounds on the MW1 Electrosmog EMF Detection Unit) in the 2,000 - 20,000 Hz range. This mish-mash of 'noise' is dependent on people making phone calls and the level can vary from very low to very high, depending on the number of calls being made at that time.

DECT cordless phones and their base units emit a 100 Hz pulsing (plus higher frequencies due to the sharp sides of the pulses); the base units do this 24 hours a day even when you are not using the phone! You can tell which houses have DECT phones by walking past them holding the MW1 Electrosmog Microwave Detection Unit.

Wireless LANs/Wi-Fi systems used to network computers and sometimes to connect to broadband internet emit their radiation in short bursts. These are heard as a scratchy pulsing/clicking noise on the MW1 which varies from a few clicks per second to an almost continuous clattering sound.

You can also hear the 50 and 100 Hz pulsing from microwave ovens and the 17 and 70 Hz pulsing from TETRA base stations, etc, etc.

Despite what some of the mobile phone operators will tell you, the MW1 does not react to electricity generating or cable sources of EMFs. Nor does it react to fluorescent lights further than at a few inches distance.

Recommended use
We suggest that you use your MW1 at full volume, when a gentle background hiss will be heard in the absence of any human-made pulsing microwave radiation from any source. Close to masts, DECT telephones, wireless LANs and other emitters, it will probably be necessary to turn the volume down until the unit is turned off or microwave shielding is installed.

There is a standard 3.5 mm stereo jack socket for an earpiece or a recording lead should you wish to record the sound your MW1 is making.

User feedback
" Dear EMFields,
Your new (MW1) audio tracking device is incredible - it is the first ‘warning’ device of low level microwave emissions affordable to most people. It is the ‘canary’ that miners had when they went down the mines - they didn’t have the ‘number measures’ of gas escape, but they knew if the canary stopped singing and died they had to get out fast! Your beam tracer does the opposite of course, screaming loudly when its detects the danger areas! Everywhere I go people (including me) are stunned by what is coming into their homes. I call it a ‘visual aid’ because when I hear the loud, terrible sounds actually in people homes, I can visualise the various beams coming off the mast/antenna. Tracing the pulsing/screaming from ceiling to floor in a room, finding the safest parts of a room to have your bed or favourite chair - what an eye-opener! Everyone’s faces are stunned when they can hear the pulsing and follow the direction of it. The whole experience shocks all your senses awake! It is a first step towards being able to protect your own home.” SW
