Computers, laptops, WiFi and video game consoles

WiFiIf the WiFi is inside your house, then your household will be exposed whenever it is on. As a rule, if no-one is using it, the exposure is generally sporadic and at fairly low levels, but when the computer is in use the exposure can rise considerably throughout the house. If your house is semi-detached, part of a terrace or in a block of flats, you can also be fairly exposed to WiFi from your neighbours house.

Computers and laptops generally give off low exposures when not using WiFi. Unearthed laptops, however, can give off very high levels of powerfrequency electric fields from the keyboard. To see if your laptop does this, you will need to buy EMFields PF5 meter. These can easily be reduced. Older generation games consoles are wired, and exposure should be minimal, but modern wireless consoles vary and would need to be measured to find out how exposed users would be. Many wireless games consoles cannot have the WiFi switched off, except by unplugging. You may want to check to see if this is the case for any systems used in your home.

The best way to check for radio frequency exposure levels (caused by most wireless devices) is to use a suitable instrument such as an Acoustimeter. You can purchase this instrument or another, cheaper (but still highly accurate) alternative such as the Acousticom 2.

We sell instruments to measure electromagnetic field exposure from sources such as electricity substations and transformers, powerlines and mobile phone masts, and offer a number of protective shielding solutions for those who find themselves highly exposed. We also provide a list of some EMF Surveyors on our surveys website.
