What I have read elsewhere is that it's comparing apples to oranges when it comes to radiation dosage. A typical x-ray machine in a doctor's office will give you a set amount of radiation and that's averaged out over your whole body to come up with the exposure number. The backscatter machines use a certain amount of radiation, and when they publish that number, they average it out over your whole body as well. But what I've read is that this is a bad comparison because the backscatter machine only penetrates a couple of millimeters. So when you average out the total radiation over the actual tissue that's being radiated, it's orders of magnitude higher for that tissue. The published numbers are simply wrong, according to what I've read. And for men, especially boys with smaller ones, the vital tissue that's being radiated at these high levels are the testicles.
I don't pretend to be knowledgeable about this, I only know what I've read. So I could be wrong, but what I've read about this leaves me with unsettled questions. I'm not confident that they have been proven safe, but based on what I know now, I would not let my son go through one.
Once some trusted entity other than the TSA shows them to be safe, I'll change my tune. But I don't trust the TSA at all to tell the truth.
