You are correct. It was to demonstrate they were wasting absurd amounts of money paying for these when they can be built fairly easily for quite a bit less.



I guess my point, from the links provided, is that we shouldn't be bombarding ourselves with the radiation these devices produce.


It's about the same as what you get from eating a banana AFAIK. At any rate, people routinely subject themselves to much higher doses of radiation.


It's actually higher than a Banana Equivalent Dose, and you can't always directly compare radiation exposure like that based on dosage.


I honestly thought that you and chc were joking about the Banana Equivalent Dose. But it turns out that it's a real concept!

Is it? A BED is about 0.08 µSv. From everything I've heard, the TSA machines dose you with somewhere between 0.02 and 0.08 µSv.
