Topband: Polarized current and interference

[Hermod Pedersen]

In a web story run by the Cleveland Plain Dealer has an interesting/dubious 
part on AC polarization and its part in radio interference. It says:

"If you are using a nonbattery radio, make sure that the electrical socket 
is polarized. If you can flip the plug over and it still fits, you don't 
have a polarized socket."

Is this really so?
If so, a huge bunch of Europeans are out of luck, as we can flip our 
sockets any way we wish.
