From the website..
As we reported yesterday, claims that the body scanners did not provide details of genitals were disproven after a London Guardian journalist who was present at a trial for the machines earlier this week reported that the devices produce an image which make “genitals eerily visible.” German Security advisor Hans-Detlef Dau, a representative for a company that sells the scanners, admits that the machines, “show intimate piercings, catheters and the form of breasts and penises”....
A report from October 2008, when the naked body scanners were first being introduced at Melbourne Airport in Australia, detailed how the X-ray backscatter devices don’t work properly unless the genitals of people going through them are visible.
