I’m anti TSA back scatter scanner, but it’s not because of the radiation, which is actually quite small. Coming in at a measure of 0.005 mrem, it’s about 1/2 of what you get by eating a banana. If you live in a brick house you are getting at least 20x that radiation level every day.

I’m anti back scatter scanner because I think it’s a 4th amendment violation, and that it’s an incredibly expensive waste of money. That money could be better spent on kitchen safety, as kitchen appliances kill more people a year than terrorists do.
