it only takes one small x-ray to start a tumour...after that you get cancer...not too mentioned your reproductive organs will become sterile

but besides the health effects, read this article: (for the horny perverts: pictures are at the bottom)

The full body scanners that President Obama last night
authorized to be rolled out in airports across the country at a cost of
over $1 billion dollars not only produce detailed pictures of your
genitals, but once inverted some of those images also display your
naked body in full living color.



And you don’t need to be a graphics wizard using a $600 software suite
like Photoshop to pull off the trick – inverting a photo is a simple
process that takes one click and is an option available even in the
most basic image editing software.



We were sent examples of the process by readers and then tested it for
ourselves to confirm that simply inverting some of the pictures
produced by the body scanners creates a near-perfect replica of a naked
body in full color.
