Once upon a time I had an great idea.
Instead of checking if my bones were broken or not for a price. I would make it totally free by putting my arms in a scanner used in a building and show the photos to an doctor friend thus make the X ray check free.
But I have heard medical ones are lot more accurate and ones used in the airports aren't high resolution enough for an medical examination.
It's been years since my teenage self thought about it and I am here.
According to some simple research. An X-Ray ay scan for arm and fingers take 0.001 mSv while an luggage scanner gives 0.04 mSv.
I don't have much information whetever the scanners used in the airports are different from the ones used in a hospital thus that's all the information I know.
