Computers and their monitors give off fairly low levels of EMFs, but if you are still worried, look out for the 2005 DELL Inspiron range of laptops which come with a three-pin mains cable and earthed adaptor and do not emit electric fields.
The biggest risk to computer users comes from broadband systems that allow ‘wireless access’ and in doing so fill your house with pulsating microwave radiation at all times.
What you can do:
All VDUs - including TVs and office computers - give off a higher level of EMFs from the back and sides, so at work, it is important to make sure you are at least 3ft away from the rear of the monitor of the colleague who sits opposite you.
