When I put a radiation-tester near an electricity socket, with nothing connected to it, it shows a large amount of electric radiation - about 800 V/m (it starts beeping and saying that the radiation is "harmful" already at 40 V/m).
When I plug in a simple 4x multi-socket (again with nothing connected to it) the radiation grows beyond 2000 V/m, which is the maximum of the radiation-tester. Moreover, even at the wall about 1 meter above the multi-socket, there is about 1000 V/m radiation; 1 meter to the right there is 100 V/m radiation (in the other directions there is no radiation at this distance).
My questions are:
- Why is the radiation so large if nothing is connected to the socket?
- Does it waste electricity, and if so, how much?
