After reading about this study conducted at MIT earlier this year, I bet you’ll think twice before Apparently, wearing a crude aluminum helmet on top of your head is the “protection of choice” among a very fringe group of paranoids, worried “Big Brother” is reading their minds. Researchers decided to test that “protective” headgear, using a $250,000 network analyzer and receiver antennae. Strangely enough, instead of dampening the connection, certain radio frequencies emanating from subjects wearing those aluminum helmets was greatly amplified and coincided with radio bands restricted for government use by the Federal Communications Commission. If you’re skeptical, think about the aluminum foil your parents placed on the ends of the “rabbit ear-style” antenna on your old black-and-white TV to get better reception, and you get the idea. Researchers suspect the “urban legend” behind the aluminum helmet may have been started by the government for a reason… Sounds more comical than threatening, don’t you think? But I am surprised they didn’t test lead foil caps, as I think that would have blocked the radio waves more effectively.
