This is not just a hypothetical possibility.  At the NCRP meeting several
years ago a speaker commented on the use of higher dose xray units  for
flouroscopy during operations, and the not rare occurrence of erythema as
a results of excessive use of the high intensity mode of these units.  On
the other hand these are usually lifesaving operations so I would presume
the main concern is simply the clinical complications to patient recovery.
