Thanks for pointing that out, but, okay, children and adolescents count too?

OP responded to a specific comment, I responded to OPs comment. I don't understand your point in that given context. I'd think showing one study - I didn't bother to look any further - that shows a risk was sufficient.

Since even adults have plenty of still dividing cells left I see it as reasonable to assume that adults are at risk too, even if that will likely be lower.

I also recommend at least the "Conclusion" section of this document, selected as an example, not as the one definite document: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3611719/ It is a good read overall too.

I don't remember the exact number but when it comes to cancer risk increase getting a regular 100 mSv x-ray as a kid counts something like 10 xrays of an adult done one after another( i.e. single dose). That's because any mutations that happen will stay with you for the rest of your life plus propagate to a lot more cells in total as your body is still growing. So while an important topic for some specialties it would be wrong to make broad statements based on this.

There is no "broad statement": There only is a specific response to a specific comment. I responded to "there is no evidence" - I don't have to show existence of 100% knowledge in the response, only that "no (zero) evidence" is not true. That is not a "broad statement", especially since I myself did not make one, only pointed to studies for the subject. Those studies don't conclude with "no evidence found".
