Here's a photography analogy.

This raises a concern about richoceting RFI.

As a film shooting photographer, I travel a lot, frequently having to get film past the TSA folks in airports. I don't want them to scan my film because unused film from previous trips is in the mix. If I kept running the film through scanners, it would eventually fog from accumulative exposure. I get hassled when I ask for a hand check of a hundred rolls at a time.

So clever manufacturers devised these lead foil lined bags that people could stuff their film in so it could ride the conveyors through the x-ray scanners.

Not a good idea.

What was found is that film fogs quicker in the bags. Some x-rays still get inside the bags, then bounce around off the inside foil, passing through the film many times. Its like a shootout in a John Wayne western, except that eveybody gets hit many times over.

If you have a wireless internet broadcaster in your house, maybe this paint isn't a good thing.
