A family in Sacramento has covered their house with sheet metal in an effort to block radio waves.

“(It’s) a shield to protect against radiation, because microwave radiation is reflected off of aluminium, so it’s a protective measure,” resident Sarah D’Souza said.

The D’Souzas said the bombardment began after the first anniversary of the Sept. 11, 2001, terrorist attacks, and that the radio waves have caused them health problems ranging from headaches to lupus.

If you examine the picture in the linked article, you’ll notice that they have a satellite dish on their roof.  Seems vaguely ironic that they’d have a dish if they were so concerned about this.  Satellite dishes receive MICROWAVE RADIATION and send it down a cable INTO THE HOUSE.  And I’m sure some small amount of MICROWAVE RADIATION leaks out of the unit, since it likely has to generate signals in this frequency range to decode the input.

I can understand some level of concern about RF exposure.  But unless they’re living next door to a satellite uplink farm or a TV station they really have nothing to worry about. 

Anyhow, the real problem here is that their sheet metal covering is UGLY, which is what the neighbors have complained about.  If they were serious about this they’d embed the covering in the walls.  It’s possible to be paranoid and stylish at the same time.
