I remember taking my kid for an x-ray of his wrist and the tech lined it all up, and then said "okay, dad and me are going over here while I take the picture."

I remember taking my kid for an x-ray of his wrist and the tech lined it all up, and then said "okay, dad and me are going over here while I take the picture." My son immediately wanted to know what the hell we just exposed to him that wasn't safe for us. In retrospect, the policy should be to let the parent stay. The risk to me is no worse than the risk to my kid. It's easy enough to explain why the tech should go behind a shield.
