To: _radsafe at radlab.nl_ (mailto:radsafe at radlab.nl) 



Dental x-ray units aren't usually used at such long exposures.  I  would 
guess you are overheating the tube. If you overheat it too badly you can  damage 
it and have one upset dentist on you hands.  I did x-ray unit  inspections for 
Oregon right after I got out of the navy.  My boss  constantly warned us about 
damaging tubes by pushing them too hard.  Dental  units are usually a fixed 
cathode rather than a rotating one such as you see in  hospitals so more prone 
to damage and  overheating.
