Totally agree that this amount of x-ray exposure without any genuine clinical justification is quite outrageous, and could eventually be dangerous to an individual's well-being.
Interesting to see the comparisons quoted by gingernut , I've never seen it put quite that way, quite so starkly, before !
Every now and again as an AME I get requests from companies or employers (usually the personnel departments) to arrange x-rays on their employees who are attending for medicals. I then usually ask the company to provide a written reason for why they are asking for the test.
Most times they decide thay won't bother !
