Found it interesting to measure the EMF on things we use everything in our lives.
This is a non-scientific observation using the Trifield 100XE EMF Meter to measure impact on EMF signal.
High amounts of EMF exposure greater than 3 have been known to link to cancer but I'm not sure how true that study is though.
The items tested are regular 6.0 DECT Uniden Cordless phone, Apple Iphone 4 and Plantronics Bluetooth 925.
You will be surprised by the results.
