Typical real-life exposures
The AM11 has been tested in hundreds of situations.
Although the highest sources in most homes are
internal, some RF EMFs come from external sources.
Indoor Domestic Readings
Most homes have 4 major sources of RF EMFS:
1) Cordless Digital (DECT) phones continuously
produce fields of up to 4 V/m at 25cm, and around
1 V/m at 1m. A few models have an eco-DECT
setting to reduce the RF when they are not in use.
2) WiFi (the access point or router plus all WiFi
devices, including smartphones and laptops, but
also fixed “smart devices”. Readings of 3 to 6 V/m
are normal at 25cm from WiFi devices, decreasing
with distance. WiFi is usually “always-on”.
3) Mobile phones. When in use, these devices can
easily produce 6 V/m at 25cm. Many ‘apps’ send
data in the background, so storing the phone in a
pocket or purse can lead to high exposures.
4) Mobile Phone Masts and other external sources
increasingly make it difficult to create a low-EMF
environment for sensitive individuals. Where there
is direct line-of-sight to a mobile phone mast from
a window, you can typically find readings of 0.2 to
over 1.0 V/m. Building construction and the mast
location and height result in large variations.
